Hello. I made quick robot managed by bluetootn to control a robot using an application 4joy- joystick
Step 1: Bluetooth Connect
Connect a bluetooth module to Arduino digital ports of 8 - RX and 9 - TX.
To work with the bluetooth module I have used the library SoftWareSerial
Step 2: Programm
The robot is controlled via bluetooth phone via 4joy-joystick applications. The program is written under the push-button gamepad buttons backward, forward, left, right - are responsible for the movement in the corresponding direction, the button A - the acceleration.
