This project shows how to control a 5V unipolar stepper motor from IR remote control uses NEC protocol with PIC18F4550 microcontroller. This controller controls the stepper motor speed and direction of rotation.
If you want to see how to drive the unipolar stepper motor using PIC18F4550 microcontroller read the following topic:
Interfacing unipolar stepper motor with PIC18F4550 microcontroller
And if you want to see how to decode IR remote control with NEC protocol see the following topic:
Extended NEC IR remote control decoder with PIC18F4550 microcontroller
To drive the unipolar stepper motor we need ULN2003 (ULN2004) Darlington transistor array or L293D motor driver as described in the previous topic.
The IR remote control used in this project is shown below:
PIC18F4550 microcontroller internal oscillator is used.
