flashing side marker lights circuit

This is a 200W lamp flasher circuit diagram. The frequency of the lamp flashing can be adjusted within a range of 1Hz to 5Hz using the PR1 variable resistor (trimpot). The duty cycle of the lamp flashing can be adjusted...

2x10 LED VU Stereo Meter

I like to see lights move to music. This project will indicate the volume level of the audio going to your speakers by lighting up LEDS. The LEDS can be any color so mix them up and really make it...

Low power long life LED flashlight Joule Thief circuit

A low power, long-life LED flashlight circuit. Electronic Design proposed a simple circuit to resolve this in a recent article. The front end of their circuit draws less than a milliamp of extra current. The described LED flashlight circuit is designed...

Mains Powered White LED Lamp

An array of white LEDs can serve as an effective small lamp for the living room. LED lamps are commercially available. LED arrays are increasingly popular for providing ambient lighting in residential spaces. The use of white LEDs in a lamp...

LED Christmas Lights Circuit

Have you already set up a Christmas tree in your house and decorated it with traditional lights? Build a couple of these LED lights to enhance the Christmas atmosphere. The project involves creating LED lights that can be used to decorate...

555 light tester circuit diagram

The circuit utilizes photoelectric sensors and a 555 timer to respond to music prompts. The illumination sensor components consist of photovoltaic cells (2CR33). When the light level drops below the optimal learning illumination of 100 lux, the 2CR33 exhibits high...

555 Astable oscillator

This free-running multivibrator utilizes an external current sink to discharge the timing capacitor, C. As a result, the interval can easily be 1000 times the pulse duration, t1, which defines a positive output. The voltage across the capacitor, V, exhibits...

220V Flashing Lamp Circuit with 555

This 220V mains operated solid-state flashing lamp circuit utilizes a 555 timer integrated circuit (IC) to manage the ON and OFF durations of a triac that regulates power to the load. The circuit operates at a mains voltage of 220V, making...

Super bright LED night light

The circuit diagram illustrates a super bright LED night lamp that operates from the mains supply. A bridge rectifier (D1) is employed to convert the AC mains voltage into DC. The combination of capacitor (C1) and resistor (R1) forms a...
