LED MOOD LIGHT CIRCUIT | Next Electronics

It consisted of 16 LEDs in a circle with two touch pads. By placing your fingers on the touch pads, the circuit started and ran the LEDs in a "chaser" pattern around the display, with a beep each time a...

LED Chaser circuit

This schematic represents a version of a simple LED chaser. A 555 timer is not utilized due to its high cost at local electronics stores, which is over $4 CAD. Instead, an oscillator is constructed using two sections of a...

Alternating-led-flasher

The alternating LED flasher is a two-transistor oscillator with LEDs connected to the collector of each transistor, allowing them to light in sync with the circuit's oscillations. The alternating LED flasher circuit utilizes a two-transistor oscillator configuration, which is a fundamental...
