This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

Last time, we used a push button to control an LED. Pressing the button turns the LED on, and releasing it turns it off. It is a very simple circuit, but Input → Arduino → Output we were able to ...

Adjusting a fan's speed using an Arduino is a great way to learn about PWM (Pulse Width Modulation) and motor control. With just a potentiometer and some simple wiring, you can create a smooth, manual ...

This exercise was demonstrated by the tutor in the video lesson, building directly on Lesson 7 by using the potentiometer's value to control an LED's brightness instead of just reading it. Reads the ...
