Testing

I've made a small circuit with a potentiometer to simulate the load to test the project. You can find a video testing the project in this link https://www.linkedin.com/posts/mahmoud158699216_embeddedsystems-arm-stm32-activity-7104739210397384705-sLWA?utm_source=share&utm_medium=member_desktop
