Rotating LED Array Circuit using IC 555 works like LED flasher and make cool rotating light if LEDs are set right. This is simple project to make but works good. We can use this circuit for decoration, emergency light or alert. This circuit gives two IC 555 pulse signal and LEDs flash in pattern. The […]
PWM LED Ramping Circuit (Slow Bright, Slow Fade)
PWM LED Ramping Circuit (Slow Bright, Slow Fade) make LED light go bright slowly and with not sudden ON/OFF This circuit is good for signal, decoration and for soft light. It uses 2× IC 555, LM393, 2N7000 MOSFET for smooth change. The circuit works best with 3 to 12V power with 6V is best. Circuit […]
Automatic Night Lamp Circuit with Photocell
Automatic night lamp use photocell to check light or dark..When dark the lamp is ON. When light the lamp goes OFF. It is good for street, garden and security lights. Parts used in circuits are LDR (ORP12), op-amp (uA741), relay which controls the AC lamp. Low light makes relay ON and lamp ON. This Automatic […]
Different Types of LEDs: A Comprehensive Guide
LED is small light. It uses less power and gives more bright. There are many type LEDs like normal, high power, RGB, SMD. Each type are used in different place like TV, torch, display and decoration. Today LED is very important in human life. Working Principle of LEDs: LED work on semiconductor principle. Inside LED […]
