LED Dimmer using IC 555 | DIY

We use LED lights almost everywhere to light up the space or a room. But sometimes, we find it difficult to deal with the brightness in the night time. So, in this project, we will see how to make a LED dimmer using IC555. We can acheived control over brightness of these LED lights according to the surroundings.


PWM Generator using IC555

Introduction, We use Pulse Width Modulation (PWM) in today’s world due to its requirement for controlling many devices in the field of Electronics. We need PWM signal widely for controlling motors, dimming LED lighting and more. Sometimes, we don’t use microcontroller in our applications. If we need to generate PWM without microcontroller then we prefer some general …
