Overview
In this lesson, we will learn how to control a stepper motor by a remote controller.
Components
- 1 * Arduino UNO
- 1 * USB Cable
- 1 * IR Receiver HX1838
- 1 * Remote Controller
- 1 * Stepper Motor
- 1 * ULN2003 Driver Board
- 1 * Breadboard
- Several jumper wires
Principle
If you press a certain key on the remote controller, the corresponding signal will be sent to the Arduino UNO, and then the Arduino can tell the stepper motor how many steps it needs to run in which direction. For example, when you press the key ‘+’, the stepper motor will run clockwise; press the key ‘-’, the motor will run counterclockwise; press the key ‘2’, it will rotate two laps; press the key ‘5’, it will rotate five laps.
Procedures
Step 1: Build the circuit
Step 2: Program
_33_control_a_stepper_motor_with_IR_remoter_controller.ino
/***********************************************************
File name: 33_control_a_stepper_motor_with_IR_remoter_controller.ino
Description: when you press the ‘0’ to ‘9’ buttons on the
remote control, you will see the stepper motor
to rotate. When you press the '+' and '-' buttons
on the remote control, you can control the stepper
motor to be forward or reverse.
