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.

Movement
Accelerometers, gyroscopes, and magnetometers are the three main sensors we use for detecting motion and orientation. We can sense motion with an accelerometer.
Accelerometers are used to measure acceleration, that means linear motion in X, Y or Z. They can be used to detect when they are being moved around, detect motion, shock or vibration. They can also be used to detect gravitational pull in order to detect orientation or tilt.
Gyroscopes are used to measure rotational motion in X, Y or Z. They are often paired with accelerometers for inertial guidance systems, 3D motion capture and inverted pendulum type applications.
Magnetometers can sense where the strongest magnetic force is coming from, generally used to detect magnetic north, but can also be used for measuring magnetic fields. When combined with accelerometers and gyroscopes you can stabilize orientation calculations and also determine orientation with respect to the Earth.
Many 6-DoF sensors, which combine accelerometer and gyroscope or compass, accelerometer and magnetometer, and 9-DoF sensors that have 9DoF IMU accelerometers and gyroscopes and magnetometers.

SparkFun Triple Axis Magnetometer Breakout – HMC5883L
This is a breakout board for Honeywell’s HMC5883L, a 3-axis digital compass. Communication with the HMC5883L is simple and all done through an I2C interface. There is no on-board regulator, so a regulated voltage of 2.16-3.6VDC should be supplied. The breakout board includes the HMC5883L sensor and all filtering capacitors as shown. The power and 2-wire interface pins are all broken out to a 0.1″ pitch header.
Magnetometers have a wide range of uses. The most common include using the chip as a digital compass to sense direction or using them to detect ferrous (magnetic) metals. Magnetic fields and current go hand-in-hand. When current flows through a wire, a magnetic field is created. This is the basic principle behind electromagnets. This is also the principle used to measure magnetic fields with a magnetometer. The direction of Earth’s magnetic fields affects the flow of electrons in the sensor, and those changes in current can be measured and calculated to derive a compass heading or other useful information.
