Bluetooth remote control for educational robotic projects with Arduino.
This control can be used for robotics and other projects. The control sends characters for steering control and also for driving a micro servo.
Characters transmitted for direction control: "w" "a" "s" "d"
Character transmitted to stop robot: "p"
Characters transmitted to control a micro-servo: "x" "b"
Bluetooth tested modules: HC-05 and HC-06
