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 […]
Simple Dark Sensor Circuit with Buzzer
A simple dark sensor circuit with a buzzer is an easy to make electronic project that can detect when there is no light and then make a sound. This kind of circuit can be used in different areas like automatic night lights, security systems and alarms. It works by using a LDR along with a […]
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 […]
Automatic Night Lamp Circuit with Photocell
This Automatic Night Lamp Circuit uses a photocell to measure how bright or dark it is around it. A night light that works with a photocell is an automatic lighting system that turns on a lamp when it gets dark and turns it off when it gets light again. This kind of setup is really […]
