The Rotating LED Array Circuit using IC 555 works like an LED flasher and creates a rotating light effect when we arrange the LEDs correctly, hence, this simple project is easy to build and delivers impressive results. Furthermore, we can use this circuit for decoration, emergency light or alert and this circuit gives two IC […]
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, as this circuit is good for signal, decoration and for soft light. Also, it uses 2× IC 555, LM393, 2N7000 MOSFET for smooth change and the circuit works best with 3 to 12V power with 6V […]
Automatic Night Lamp Circuit with Photocell
Automatic night lamp use photocell to check light or dark; when dark the lamp is ON and when light the lamp goes OFF. This type of circuit is good for street, garden and security lights and also the parts used in circuits are LDR (ORP12), op-amp (uA741), relay which controls the AC lamp. Also, low […]
Different Types of LEDs: A Comprehensive Guide
LEDs are small light sources that consume less power and produce high brightness. Different types of LEDs, such as standard LEDs, high-power LEDs, RGB LEDs, and SMD LEDs, serve various applications, including TVs, flashlights, displays and decorative lighting. Therefore, today LED is everywhere and is very important part in human life. Working Principle of LEDs: […]
Transistors Based Megaphone Circuit
To begin with, this Transistors Based Megaphone Circuit uses transistor like amplifier, as it take weak sound from MIC and makes loud sound in speaker. People also use it in public talks, sports events and rallies wherever they need a loud voice; the circuit additionally uses two TIP32 transistors in a push-pull configuration to boost […]
Adjustable Thermostat Circuit using IC LM56
An electronic adjustable thermostat controls temperature in heating or cooling systems, as this adjustable thermostat circuit uses the low-power IC LM56 chip to switch between two temperature modes. First, it controls outside transistor for output load and then IC LM56 give reliable, precise temperature control. Moreover, it is good for many uses like check temperature […]
