Arduino Bluetooth Remote Lite

Un controlador de bluetooth básica simple para Arduino dispositivos de motor DC basa

This sample sketch is for Arduino based bluetooth tank with the following components, feel free to modify the code to suit your DIY project. Happy building!

1) Arduino UNO R3

2) Motor Driver (2A Dual L298N H-Bridge)

3) HC06 Bluetooth Module

Note: Disable bluetooth power when uploading sketch

Data sent while pressing button:

Up = w

Down = x

Left = a

Right = d

Cannon left = q

Cannon right = e

While release button will sent out = s
