Controlling Stepper Motor With Remote

Search…

In this lesson, you will learn a fun and easy way to control a stepper motor from a distance using an IR remote control.

Overview
In this lesson, you will learn a fun and easy way to control a stepper motor from a distance using an IR remote control.
The stepper we are using comes with its own driver board making it easy to connect to our UNO R3.
The IR sensor is connected to the UNO R3 directly since it uses almost no power.
Component Required
1 x Arduino UNO R3
1 x IR receiver module
1 x IR remote
1 x ULN2003 stepper motor driver module
1 x Stepper motor
7 x F-M wires (Female to Male DuPont wires)
2 x M-M wire (Male to Male jumper wire)
