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.

Moteino in RFM12B to rebuild suggests doing as new without completely replacing. I decided to stripped down at RFM12B and rebuild in Bluetooth.

MPU-9150

MotionInterface is becoming a “Must-Have” function being adopted by smartphone and tablet manufacturers due to the enormous value it adds to the end user experience. In smartphones, it finds use in applications such as gesture commands for applications and phone control, enhanced gaming, augmented reality, panoramic photo capture and viewing, and pedestrian and vehicle navigation. With its ability to precisely and accurately track user motions, MotionTracking technology can convert handsets and tablets into powerful 3D intelligent devices that can be used in applications ranging from health and fitness monitoring to location-based services. Key requirements for MotionInterface enabled devices are small package size, low power consumption, high accuracy and repeatability, high shock tolerance, and application specific performance programmability, all at a low consumer price point.

SparkFun Bluetooth Mate Silver

The Bluetooth Mate is very similar to our BlueSMiRF modem, but it is designed specifically to be used with our Arduino Pros and LilyPad Arduinos. These modems work as a serial (RX/TX) pipe, and are a great wireless replacement for serial cables. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target.

Bluetooth Mate has the same pin out as the FTDI Basic, and is meant to plug directly into an Arduino Pro, Pro Mini, or LilyPad Mainboard. Because we’ve arranged the pins to do this, you cannot directly plug the Bluetooth Mate to an FTDI Basic board.

The RN-42 is perfect for short range, battery powered applications. The RN-42 uses only 26uA in sleep mode while still being discoverable and connectable. Multiple user configurable power modes allow the user to dial in the lowest power profile for a given application. The Bluetooth Mate has on-board voltage regulators, so it can be powered from any 3.3 to 6VDC power supply. We’ve got level shifting all set up so the RX and TX pins on the remote unit are 3-6VDC tolerant.

4×4 Offroad Race

3D off-road racing game. Powerful off-road vehicles, trails and routes running on dirt roads, extreme weather conditions and violent opponents, all that we call 4×4 Offroad Race. You will be able to experience the most powerful four-wheel drive vehicles. You have to overcome terrible roads, do jumps over bumps and potholes and knock opponents off the track to win all the races.

SparkFun Joystick Shield Kit

The SparkFun Joystick Shield Kit contains all the parts you need to enable your Arduino with a joystick. The shield sits on top of your Arduino and turns it into a simple controller. Five momentary push buttons and a two-axis thumb joystick gives your Arduino functionality on the level of old Nintendo controllers. Soldering is required, but it’s relatively easy and requires minimal tools. We even have a step by step guide.

The momentary push buttons are connected to Arduino digital pins 2-6; when pressed they will pull the pin low. Vertical movement of the joystick will produce a proportional analog voltage on analog pin 0, likewise, horizontal movement of the joystick can be tracked on analog pin 1.

Joystick

A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick. Joysticks are also used for controlling machines such as cranes, trucks, underwater unmanned vehicles, wheelchairs, surveillance cameras, and zero turning radius lawn mowers. This is a joystick very similar to the analog joysticks on PS2 controllers. Directional movements are simply two potentiometers, one for each axis. Pots are 10k Ohm each. This joystick also has a select button that is actuated when the joystick is pressed down.

Bluetooth

Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks. It employs UHF radio waves in the ISM bands, from 2.402 GHz to 2.48 GHz. It is mainly used as an alternative to wire connections, to exchange files between nearby portable devices, computer and connect cell phones and music players with wireless headphones. In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres.
