keyestudio 4WD Bluetooth Multi-functional Car is a learning application development system based on microcontroller and with ATmega-328 as core. It has functions of line tracking, obstacle avoidance, IR remote control , Bluetooth remote control and detecting distance.

This kit contains plenty of interesting programs and can extend an external circuit module to increase more functions of this car. The kit aims to disengage users from boring theories and obtain capacity of system development when learning Arduino.


1. Motor: Voltage: 6-9V        Reduction Ratio: 1:48 
2. Choosing L298N driver module as control motor, separated from microcontrollor.
3. Three line tracking modules have higher precision when detecting white and black lines, able to realize anti-falling.
4. IR remote control module making up a remote control system of the car
5. Using ultrasonic module to realize obstacle avoidance
6. Pairing mobile phone Bluetooth with Bluetooth remote control module to control the car
7. Able to connect with external voltage at 7~12V, and equipped with various sensors to complete different functions as much as possible
