A circuit that works as a Light Controlled Switch uses the LM311 integrated circuit along with a Light Dependent Resistor (LDR). This circuit is simple but very useful because it reacts to changes in light levels around it. You can find this kind of circuit in many places, like automatic lights, street lamps and security […]

A mini flasher circuit that uses the IC 555 timer represents a simple electronic assembly designed to cause an LED to emit light in a blinking pattern at a specified frequency. This type of circuit finds frequent application in various indicator systems, signaling apparatus and projects undertaken by hobbyists. The construction of this circuit utilizes […]
Simple Micro Flasher Circuit using IC CD 4093
A simple micro flasher circuit using the CD 4093 integrated circuit is an easy way to make an LED blink perfect for many indicator uses. This circuit takes advantage of the CD 4093 IC, which has four NAND Schmitt trigger gates. It runs on a 6V battery and only needs a few extra parts making […]
PWM Based Lamp Brightness Controller Circuit
A circuit that controls how bright a lamp shines using pulse width modulation PWM is super useful for anyone who wants to adjust the light of an incandescent lamp to their liking. This PWM Based Lamp Brightness Controller Circuit uses a 555 timer chip set up as an astable multivibrator which helps manage how bright […]
Rotating LED Array Circuit using IC 555
The Rotating LED Array Circuit using IC 555 described here is cleverly designed to work as an LED flasher, which can create a cool rotating light effect if the LEDs are set up correctly. This LED design is simple but very effective making it great for different uses like decoration, emergency lights, or visual alerts. […]
PWM LED Ramping Circuit (Slow Bright, Slow Fade)
An PWM LED Ramping Circuit helps change the brightness of an LED smoothly, so it lights up gradually instead of just turning on and off suddenly. This smooth lighting effect is really useful for many things, like visual signals, decorative lights and soft signaling systems. The circuit shown here uses two IC 555 timers, an […]
