230V AC dimmer, mains isolated, using PIC12F629
https://www.electronics-lab.com/230v-ac-dimmer-mains-isolated-using-pic12f629/
This is a very simple mains isolated dimmer with a triac output (phase control). It uses timer0 to do the timing. There is no user interface, the value of the triac ignition delay after a zero crossing is defined by setting the reload value of timer0 (Tmr0) in the software directly. This value can e.g. […]
12V NE555 PWM Controller
https://www.electronics-lab.com/12v-ne555-pwm-controller/
baelza.bubba @ instructables.com build his own PWM controller which is able to operate as a 12V Motor Speed Controller, LED Dimmer, Heat controller, voltage controller for an electrolytic etcher etc. I did some hunting around on the interweb and found a pretty good starting point in Circuits Today, but then, I needed to make […]
AC PWM dimmer for Arduino
https://www.electronics-lab.com/ac-pwm-dimmer-for-arduino/
diy_bloke @ instructables.com has designed an AC PWM dimmer for Arduino: Over 3 years ago, I published a simpel TRIAC AC dimmer for the arduino. That proved to be a very popular design. Yet in spite of the simplicity of the circuit the software needed was a bit complicated as it needed to keep track of […]
Arduino controlled Triac light dimmer
https://www.electronics-lab.com/arduino-controlled-light-dimmer/
diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not really possible due to the large […]
PWM dimmer for RGB LED
https://www.electronics-lab.com/pwm-dimmer-for-rgb-led/
Lukas Fassler has designed and built a PWM dimmer for RGB LED: In my last post I’ve described the design and construction of my LED dimmer project. This project here is similar but a bit more involved. It controls RGB LEDs so it can not only change the brightness but also the color of the […]
PWM dimmer for LED lighting
https://www.electronics-lab.com/pwm-dimmer-for-led-lighting/
Lukas Fassler has published a new project, a DIY PWM dimmer for LED lighting. The dimmer can handle 100W@12V and is controlled by a single potentiometer. I have recently moved to a new penthouse and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be easy enough nowadays […]

Basic Types of Thyristors and Applications
https://www.electronics-lab.com/basic-types-of-thyristors-and-applications/
In this article we will discuss about the various types of thyristors. Thyristors are 2 pin to 4 pin semiconductor devices that act like switches. For example a 2 pin thyristor only conducts when the voltage across its pins exceeds the breakdown voltage of the device. For a 3 pin thyristor the current path is […]
Automatic Light Switching System with Dimmer
https://www.electronics-lab.com/automatic-light-switching-system-with-dimmer/
Manual switching of outdoor lights in houses or roadways can be sometimes really inconvenient especially when we are far away or still at work. Sometimes this becomes an opportunity for thieves to infiltrate houses or a possibility of accident in roadways if night comes and our outdoor lights are still OFF. That is why the […]
