You can control the brightness of these LEDs using variable resistors VR1, VR2 and VR3 respectively. Parts Needed. Arduino UNO board – 1 ; 5mm LEDs Red, Green, Blue – each 1 ; 100K Variable resistor – ...

Temperature Controlled Fan Using Arduino This project demonstrates the development of an energy-efficient system to regulate a fan's speed automatically based on room temperature. By integrating an ...

This project demonstrates a system using two Arduino boards, an LM35 temperature sensor, and an L298N motor driver to control a DC motor's speed and direction based on temperature readings. The setup ...

A PWM voltage regulator is built using a LM2596 buck converter which is driven by the PWM signal from the Arduino. By mapping the LDR output values to the PWM signal duty cycle the LED light intensity ...

This project is perfect for beginners, and we'll use LDR sensor modules to detect light and an MX1508 motor driver module for control. By building this simple light following robot you will learn the ...
