This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

This laboratory report has 4 different laboratory sessions and at the end of the laboratory sessions we aim to control the fan speed. In the first laboratory session we established that how Arduino ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Arduino script to control a 5V Noctua A6x25 PWM fan (or any other 5V PWM fan) with the onboard Arduino Leonardo on an Udo Bolt. I got one of the first Udoo Bolts in 2019. As its fan was horribly noisy ...

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will ...
