Controlling_180°Motor

This project lets you control a 180° servo motor with a joystick and a potentiometer, is it useful by itself? No, but that's not my problem.

Project description

Code

DaCode

c_cpp

The map function converts 0-1023 to 0-180 because the joystick/potentiometer can input a value from 0 to 1023 while the motor can move from 0 to 180 degrees.

I just realized my circuit images are horrible.

In this circuit I show you the potentiometer version, you can replace it with the joystick just by connecting the red wire to 5v, the blue one to GND and the green one to the x or y axys pin; you could also use both the joystick and the potentiometer at the same time by connecting them both to A0.
