I'm sure that each of you can find at home unused RC car. This instruction will help you change your old RC car to original gift :) Due to the fact that the RC car I had was small in size I have chosen Arduino Pro Mini as a main controller. Another important module that I've used in this project is TB6612FNG dual motor driver carrier. This motor controller has sufficient range of acceptable input voltages (4.5V to 13.5V) and continuous output current (1A per channel). As a bluetooth receiver I used a popular inexpensive module HC-06. Additionally, you can use LEDs as front and rear lights of the car.
Components of the project:
The way of connecting Arduino Pro Mini with the other modules is given below. Don't forget to connect the supply voltage to each module (VCC, GND).
1. Bluetooth (e.g. HC-06) -> Arduino Pro Mini (3.3V)
2. TB6612FNG Dual Motor Driver -> Arduino Pro Mini
3. TB6612FNG Dual Motor Driver -> DC Motors
4. LEDs -> Arduino Pro Mini
