RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. This project is open-source and can be freely used for educational purposes. I demonstrate ...

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 water level and temperature monitoring system uses contact or non-contact water level sensors along with a probe-type temperature sensor. A digital display provides continuous, real-time ...

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 ...

In this video I'll be showing you how you can control the contrast and the back light brightness of a 1602 LCD display with just the Arduino. The contrast is typically adjusted with a variable ...
