I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

This project uses two Arduino boards to control the speed of a DC fan using a potentiometer. Three LEDs indicate different speed ranges: red for slow, green for medium, and blue for fast. The serial ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

This project is an automated kitchen safety and ventilation system built using an Arduino UNO R3, a DHT22 temperature & humidity sensor, an MQ-2 gas/smoke sensor, and a relay module connected to an AC ...

Whether you’re using a soldering iron or a table saw, ventilation in the shop is important. Which is why [Atomic Dairy] built a monster air cleaner called the Fanboy that looks like it should be ...
