Send and Receive

These RF Transmitter Modules are very small in dimension and have a wide operating voltage range. The low cost RF Transmitter can be used to transmit signal up to 100 meters. It is good for short distance, battery power device development. These wireless transmitters work with 433 MHz receivers. They are breadboard friendly and also work great with microcontrollers to create a very simple wireless data link.

Amplitude-Shift Keying

Amplitude-Shift Keying, or ASK, is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave. In an ASK system, a symbol, representing one or more bits, is sent by transmitting a fixed-amplitude carrier wave at a fixed frequency for a specific time duration. For example, if each symbol represents a single bit, then the carrier signal could be transmitted at nominal amplitude when the input value is 1, but transmitted at reduced amplitude or not at all when the input value is 0.

These modules use a technique known as Amplitude Shift Keying to transmit digital data over the radio. In amplitude shift keying, the amplitude of the carrier wave, 433 MHz signal in our case, is modified in response to an incoming data signal.

Radio Receiver

In radio communications, a radio receiver, also known as a receiver, a wireless, or simply a radio, is an electronic device that receives radio waves and converts the information carried by them to a usable form. It is used with an antenna. The antenna intercepts radio waves and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information. The receiver uses electronic filters to separate the desired radio frequency signal from all the other signals picked up by the antenna, an electronic amplifier to increase the power of the signal for further processing, and finally recovers the desired information through demodulation.

Full Duplex

A simple illustration of a full-duplex communication system. Full-duplex is not common in handheld radios as shown here due to the cost and complexity of common duplexing methods, but is used in telephones, cellphones and cordless phones. A full-duplex (FDX) system allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously.

Land-line telephone networks are full-duplex since they allow both callers to speak and be heard at the same time. Full-duplex operation is achieved on a two-wire circuit through the use of a hybrid coil in a telephone hybrid. Modern cell phones are also full-duplex.

There is a technical distinction between full-duplex communication, which uses a single physical communication channel for both directions simultaneously, and dual-simplex communication which uses two distinct channels, one for each direction. From the user perspective, the technical difference doesn’t matter and both variants are commonly referred to as full duplex.

Radio Frequency

Radio Frequency (RF) is the oscillation rate of an alternating electric current or voltage or of a magnetic, electric or electromagnetic field or mechanical system in the frequency range from around 20 kHz to around 300 GHz. This is roughly between the upper limit of audio frequencies and the lower limit of infrared frequencies, these are the frequencies at which energy from an oscillating current can radiate off a conductor into space as radio waves. Different sources specify different upper and lower bounds for the frequency range. Energy from RF currents in conductors can radiate into space as radio waves. This is the basis of radio technology.

Duplex Telecommunications

A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment of equipment in the field. There are two types of duplex communication systems: full-duplex (FDX) and half-duplex (HDX).

ISM Radio Band

The ISM radio bands are portions of the radio spectrum reserved internationally for industrial, scientific and medical (ISM) purposes, excluding applications in telecommunications. Examples of applications for the use of radio frequency (RF) energy in these bands include radio-frequency process heating, microwave ovens, and medical diathermy machines. The powerful emissions of these devices can create electromagnetic interference and disrupt radio communication using the same frequency, so these devices are limited to certain bands of frequencies. In general, communications equipment operating in ISM bands must tolerate any interference generated by ISM applications, and users have no regulatory protection from ISM device operation in these bands.

RFM12B Universal ISM Band FSK Transceiver

Hoperf is RFM12B is a single chip, low power, multi-channel FSK transceiver designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 433, 868 and 915 MHz bands. The RFM12B transceiver is a part of Hoperf EZRadio product line, which produces a flexible, low cost, and highly integrated solution that does not require production alignments. All required RF functions are integrated. Only an external crystal and bypass filtering are needed for operation.

Moteino

Moteino began as a low power wireless Arduino compatible development platform based on the popular ATmega328p chip used in the Arduino UNO. Moteinos are compatible and can communicate with any other Arduino or development platform that uses the popular HopeRF RFM69 or LoRa transceivers, or even the older RFM12B. Moteino also comes with an optional SPI flash memory chip for wireless programming, or data logging. Moteino was designed to be a compact, highly customizable and affordable development platform, suitable for IoT, home automation and long range wireless projects.

Programming and Coding

Most of the development in the world is all because of technology. Technology has grown much faster than everything else. All the technology is developed because of coding and programming. Programming and coding hold a vital role in development. It also includes developments from small projects to big projects.

The programming vs coding difference lies in the very definition of both processes. Programming is the general process of creating a program that follows certain standards and performs a certain task. Coding, on the other hand, is a part of programming that deals strictly with converting the language we understand into binary commands for the machine.

As we have discussed before in our discussion on programming vs coding, coding is just a part of programming. Yet, it still requires some time and skill to learn. Programming languages are very different from natural languages, and their syntax can sometimes be very confusing. The hardest languages are low-level ones that are close to actual processor instructions.

Programming

Programmers, on the other hand, need to review documentation and perform analysis besides coding which requires extra tools. You can find various code analysis tools, code generators, databases and testing frameworks in their inventory. Programming is passing the instructions and information to the computer that describes how a program should be carried out. Programming helps computers to perform certain actions. Various types of programming languages available in the market, like C, C++, Java, Python, etc., help develop new and creative technology.

Coding

Since coding is a simple act of translation, you don’t need much to perform it. In most cases, a simple text editor would suffice. Coding is a process of establishing a successful communication between a software program and the computer hardware. The compilers translate the program into assembly language. The coding process converts the assembly language to Binary Coded Signals.

Computer systems are electronic devices that rely on binary coded signals for communication and functioning. The two types of binary coded signals are o’s and 1’s. These signals are generated using switches and transistors. In the process of coding the high-level language and the assembly level languages are translated into binary codes and the communication between the computer hardware and software application is established.

Microcontrollers – Arduino IDE

Since the launch of the Arduino open-source platform, the brand has established themselves at the center of an expansive open-source community. The Arduino ecosystem is comprised of a diverse combination of hardware and software. The versatility of Arduino and its simple interface makes it a leading choice for a wide range of users around the world from hobbyists, designers, and artists to product prototypes.

Arduino code is written in C++ with an addition of special methods and functions, which we’ll mention later on. C++ is a human-readable programming language. When you create a “Sketch”, the name given to Arduino code files. The Arduino Integrated Development Environment (IDE) is the main text editing program used for Arduino programming. It is where you’ll be typing up your code before uploading it to the board you want to program. Arduino coding it is processed and compiled to machine language.

Quaternion

In mathematics, the quaternion number system extends the complex numbers. Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in three-dimensional space. Hamilton defined a quaternion as the quotient of two directed lines in a three-dimensional space, as the quotient of two vectors. Multiplication of quaternions is noncommutative.

Quaternions are used in pure mathematics, but also have practical uses in applied mathematics, particularly for calculations involving three-dimensional rotations, such as in three-dimensional computer graphics, computer vision, and crystallographic texture analysis. They can be used alongside other methods of rotation, such as Euler angles and rotation matrices, or as an alternative to them, depending on the application.

SparkFun 9 Degrees of Freedom Breakout – MPU-9150

The SparkFun 9DOF MPU-9150 is the world’s first 9-axis MotionTracking MEMS device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors. And guess what? You get to play with it.

This breakout board makes it easy to prototype with the InvenSense MPU-9150 by breaking out all the pins you need to standard 0.1″ spaced headers. The board also provides I2C pullup resistors and a solder jumper to switch the I2C address of the device.

The MPU-9150 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, 3-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex MotionFusion algorithms; and the AK8975, a 3-axis digital compass. The part’s integrated 6-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data.

Inertial Measurement Unit

An inertial measurement unit (IMU) is an electronic device that measures and reports a body’s specific force, angular rate, and sometimes the orientation of the body, using a combination of accelerometers, gyroscopes, and sometimes magnetometers. When the magnetometer is included, IMUs are referred to as IMMUs. IMUs are typically used to maneuver modern vehicles including motorcycles, missiles, aircraft, including unmanned aerial vehicles, among many others, and spacecraft, including satellites and landers. Recent developments allow for the production of IMU-enabled GPS devices. An IMU allows a GPS receiver to work when GPS-signals are unavailable, such as in tunnels, inside buildings, or when electronic interference is present.

AltIMU-10 v5 Gyro, Accelerometer, Compass, and Altimeter (LSM6DS33, LIS3MDL, and LPS25H Carrier)

The Pololu AltIMU-10 v5 is an inertial measurement unit (IMU) and altimeter that features the same LSM6DS33 gyro and accelerometer and LIS3MDL magnetometer as the MinIMU-9 v5, and adds an LPS25H digital barometer. An I²C interface accesses ten independent pressure, rotation, acceleration, and magnetic measurements that can be used to calculate the sensor’s altitude and absolute orientation. The board operates from 2.5 to 5.5 V and has a 0.1″ pin spacing.

Roll, Pitch, and Yaw

How is Controlling an Airplane or Robotic Different than Controlling a Car or Boat?

Stability and control are much more complex for an airplane, which can move freely in three dimensions, than for cars or boats, which only move in two. A change in any one of the three types of motion affects the other two.

Imagine three lines running through an airplane and intersecting at right angles at the airplane’s center of gravity.

  • Rotation around the front-to-back axis is called Roll.
  • Rotation around the side-to-side axis is called Pitch.
  • Rotation around the vertical axis is called Yaw.

SparkFun 9 Degrees of Freedom – Sensor Stick

The SparkFun 9DOF Sensor Stick is a very small sensor board with 9 degrees of freedom. It includes the ADXL345 accelerometer, the HMC5883L magnetometer, and the ITG-3200 MEMS gyro. The “Stick” has a simple I2C interface and a mounting hole for attaching it to your project. Also, the board is a mere allowing it to be easily mounted in just about any application.

Gyroscope

A gyroscope is a device used for measuring or maintaining orientation and angular velocity.It is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum.

Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices, solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. MEMS gyroscopes are popular in some consumer electronics, such as smartphones.

SparkFun Tri-Axis Gyro Breakout – L3G4200D

This is a breakout board for the L3G4200D low-power three-axis angular rate sensor. The L3G4200D is a MEMS motion sensor and has a full scale of ±250 or ±500 or ±2000 dps and is capable of measuring rates with a user selectable bandwidth. These work great in gaming and virtual reality input devices, GPS navigation systems and robotics.

Accelerometer

An accelerometer is a tool that measures proper acceleration. Proper acceleration is the acceleration of a body in its own instantaneous rest frame, this is different from coordinate acceleration, which is acceleration in a fixed coordinate system. For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth’s gravity, straight upwards 9.81 m/s2. By contrast, accelerometers in free fall, falling toward the center of the Earth at a rate of about 9.81 m/s2, will measure zero.

Accelerometers have many uses in industry and science. Highly sensitive accelerometers are used in inertial navigation systems for aircraft and missiles. Vibration in rotating machines is monitored by accelerometers. They are used in tablet computers and digital cameras so that images on screens are always displayed upright. In unmanned aerial vehicles, accelerometers help to stabilise flight. Micromachined microelectromechanical systems accelerometers are increasingly present in portable electronic devices and video-game controllers, to detect changes in the positions of these devices.

SparkFun Triple Axis Accelerometer Breakout – ADXL335

Breakout board for the 3 axis ADXL335 from Analog Devices. This is the latest in a long, proven line of analog sensors, the holy grail of accelerometers. The ADXL335 is a triple axis MEMS accelerometer with extremely low noise and power consumption, only 320uA. The sensor has a full sensing range of +/-3g. There is no on-board regulation, provided power should be between 1.8 and 3.6VDC. Board comes fully assembled and tested with external components installed. The included 0.1uF capacitors set the bandwidth of each axis to 50Hz.
