I just built an RC car with an arduino, a bluetooth HC-05 Module and a L298 motor controller. I can control it via Bluetooth but the issue occurs when i release a button. Since the arduino receives commands via serial from the module, It continues to drive when I release the button from the app as the value is still in the Serial. I’m using the arduino bluetooth controller app on android. Here’s my code.
