Android class final project - phone accelerometer controlled, LiPo powered vehicle!

CS414FinalProject-Arduino

Synopsis

This is the Arduino driver code for my Android class final project. This code handles setting up and driving the motors of the bot, as well as handling the communication between the phone and Arduino through Bluetooth.

This is the meat of the project, the companion phone app can be found here: CS414FinalProject-Android

If you'd like a detailed breakdown of the project, the challenges, and the solutions, checkout the project report: Final Project Report

Most if not all project parts are listed below, so check them out if you're interested and want to take a go at building one!

Thanks for checking out the repo, happy coding!

Parts / Supplies

A list of the parts needed to build this project can be found below. Please, please, please, take the time to search and watch how to PROPERLY and SAFELY handle, charge and discharge LiPo / Lithium Ion batteries.

• LiPo Battery Charge / Care

Also, you will need some sort of chassis or support platform to mount the wheels and the other parts. Below is a link to a potential chassis, and included is a number of the parts listed below, but the parts below require no - minimal soldering, so more plug and play.

• 2WD Smart Robot Car Chassis Kit

Would also recommend using a hot glue gun for mounting the motors! If not hot glue then command strips, but you will probably end up needing to reinforce them quite often for the wheels to not come loose or out of alignment.

• Hot Glue Gun Kit
• Command Strips

Parts

• Arduino MEGA R3
• 2 x 11.1V 3S 850mAh 75C LiPo Batteries
  • You can get a larger capacity battery if needed (i.e > 850mAh), but make sure to then also buy a compatible charger and connector plugs
  • You can also get a higher voltage battery if needed (i.e > 11.1V), but make sure to step down the voltage for the Arduino to between 7-12V; as well as for the Motor Driver between 5-40V
    • Note: If using TT motors, driving motors with more than 25-30V, you will probably burn out your motors. Check your motors datasheet to see what the max input voltage the motors can take is.
• LiPo Battery Balance Charger
  • If you can spare the extra expense, go with this charger: ISDT Q6 Nano Lipo Battery Charger/Discharger
• XT30 Plug Connectors
• DC-DC Voltage Regulators
• L298N Motor Drivers
• TT DC Gearbox Motors
• HC-06 Bluetooth Module
• Breadboard Jumper Wires

Optional Parts but HIGHLY recommended

• Lipo Battery Safe Bag
• Lipo Battery Voltage Checker
  • Be PREPARED these things are loud when the alarm goes off
