COMPONENTS AND SUPPLIES Arduino UNO & Genuino UNO × 1 L298 Motor Controller × 1 Bluetooth Module × 1 RC Car × 1 ABOUT THIS PROJECT Project: This project was an interesting endeavor, as it was mostly a guess and check routine until I found out what worked for me in the long-run. I used the Adafruit Bluetooth LE tutorial to figure out how to hard-wire this setup, and used Michael's hybrid code to power the motors and steering. First off, here is the video of the working car! The hardware setup for the Bluetooth module is as follows: Fritzing diagram (from the Adafruit tutorial): Not much is being accomplished with this photo. The L298 Motor Controller was connected to a 9V battery, the Arduino ground and 5V, and pins 6, 7 and 8 (to pins enB, in4 and in3, respectively). The microservo used for steering was connected to digital pin 3, and the Arduino ground and 5V connections. ...
