The most popular display system widely used in Arduino projects is the liquid crystal display (LCD). LCD displays consists primarily of two sheets of polarized glass plates with a thin layer of liquid ...

This project controls a system that monitors temperature using a temperature sensor (connected to pin A0) and displays the temperature on an LCD screen. It also features LED indicators (green, yellow, ...

This project is a standalone automatic fan speed controller that regulates the speed of an electric fan based on temperature requirements. It utilizes embedded technology to create an efficient and ...

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 ...
