Puff to OFF LED circuit

This circuit features an LED that can be turned off with a puff of air. A condenser microphone (M1) detects the puff. When the push button switch S1 is activated, transistors Q2 and Q3, configured as a latching pair, are...

220V Flashing LED Circuit

An AC mains operated single LED flasher circuit is constructed using the widely utilized CMOS timer chip TLC555. The entire circuit is powered directly from the 230VAC grid supply via a capacitive potential divider and associated components. This compact LED...

LED Pumpkin Candles for Colorful Halloween Jack-O-Lanterns

Discrete blinking LEDs are convenient, but the blink rate and duration are not configurable. Experimentation with transistors, resistors, and capacitors was attempted to modify the blinking LED behavior. Ultimately, the abundance of additional electronic components led to the conclusion that...

Lm3485 Led Demo Board

The LM4550 is an audio codec designed for PC systems, fully compliant with PC99 standards, and performs the analog-intensive functions of the AC97 Rev2.1 architecture. It utilizes 18-bit Sigma-Delta analog-to-digital (A/D) and digital-to-analog (D/A) converters, providing a dynamic range of...

220V AC Powered White Led Lamp

The circuit provides sufficient illumination suitable for reading purposes. Capacitor CX, in conjunction with diodes D1 through D4, constitutes the AC step-down circuit. CX lowers the high voltage AC from the mains to a low voltage AC, which is subsequently...

LED Audio VU Meter

This project is also an essential part of the expandable analyser to be published soon or perhaps eventually, and one meter circuit is used for each frequency band. There are many other uses for a simple LED VU meter. They...

Christmas light circuit

The chart illustrates a Christmas lights circuit that employs a simple and cost-effective CD4069 CMOS hex inverter to control four separate circuits, each consisting of 50 light-emitting diodes (LEDs), totaling 200 LEDs. The circuit is powered directly by a 220V...
