TLROB003

Shruti wanted to gift a remote control car to her brother on his birth day. Instead of remote she thought to make a car that can be controlled by cell phone. Can you help her to make a mobile controlled car?

Robo Car chassis Kit

Attach 2 motors and caster wheel to the chassis.
Create a system of motor driver IC, bluetooth sensor and arduino UNO.
Code on arduino IDE. (for connection and code take help of let's tinker app)
Install app Arduino Bluetooth from play store.
Map the button values with app.
