In this article, the Sound to Light Converter Circuit changes sound into light, as a result, it listens to music and makes the lights flash in sync with the beat. Furthermore, smart components inside the circuit convert changes in sound volume or pitch into variations in light brightness or flashing speed. Circuit Working of Sound […]

LED Chaser Circuit using Transistors
Think of flashing lights in a line but with LEDs and not with bulbs! as this LED Chaser Circuit using Transistors makes LEDs light up one by one like running. Furthermore, it uses small switches called transistors to control LEDs and also this circuit is good for beginners and is fun way to learn how […]
How to use an LED as a Light Detector Circuit
LEDs mostly make light but they can also sense light! Like a secret power, when light hits an LED in the right way, it generates a small amount of electricity; scientists call this phenomenon the photovoltaic effect, which works like a tiny solar panel. In this post for How to use an LED as a […]
Simple CFL Driver Circuit
CFL bulb need special helper circuit to turn ON and glow bright, as this Simple CFL Driver Circuit change home electricity into power CFL can use. Furthermore, CFL bulb uses little mercury vapor to make invisible light and then it hits special powder to make light we see. Circuit Working: Parts List: Components Values Quantity […]
3V LED Driver Circuit using IC LT1937
To begin with, this 3V LED Driver Circuit using IC LT1937 is a compact LED driver because it uses the LT1937 IC, which can power a white LED from only a 3V battery. Furthermore, the IC takes a low input voltage and boosts it to the level required by the LED. As a result, the […]
Simple LED Constant Current Circuit
Just think like water pipe filling bucket. Normal circuit is like set water pressure voltage and hope the bucket fills good, but with LED this Simple LED Constant Current Circuit is like smart nozzle. It keep water flow current same even if pressure changes a little and this way LED light up nice and live […]
