Bluetooth-Controlled Car

ECE 3140

For my ECE 3140 Embedded Systems final project, I developed a remote-controlled toy car using two bluetooth modules and two ARM FRDM-K64F microcontrollers.

Details: A remote controller with 4 push-buttons communicates with one MPU and sends direction and speed data over an HC-05 bluetooth module.

Another MPU on the robot receives data via a paired HC-05 module and performs speed and direction motor control by generating two PWM outputs. A power management system feeds the on-board electronics and an h-bridge which controls two motors.
