RFID Module: Reads the UID from an RFID tag/card. If the UID matches the authorized UID, access is granted. Ensure the RFID tag/card UID matches the authorized UID in the code. Use the potentiometer ...

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 ...

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 ...

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 ...
