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, ...

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 ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

Abstract: This paper presents designing and implementing an Automatic room temperature control system using the Arduino and DHT11 sensor. The fan speed control system has also been proposed. Here, the ...
