This project is a simple LED dimmer circuit that uses Arduino's PWM (Pulse Width Modulation) capability. The user can smoothly adjust the brightness of an LED using a potentiometer or digital input.

This program is useful for creating an energy-efficient lighting system that responds to motion, such as a hallway or security light, with adjustable brightness and automatic turn-off features after a ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

An LED dimmer circuit adjusts the brightness of LED strips, serving both as an energy-saving tool and a method to create aesthetic lighting. Call bells, designed to draw attention, are commonly used ...
