An R/C car using Bluetooth and an LD293 chip 

This project is an adaptation on a familiar theme and was my first attempt at a fairly large-scale Arduino-based motor controller.

This project was created with the red car robot chassis, a breadboard, an ld293 series chip for forward and rear-control. 

It also employs the enabled pins on the LD293  for PWM speed control.

It uses a custom, but simple, Appinventor phone app to control the car.


The code and diagrams will be more instructive than I can be in this short introduction.
