This is a simple LED driver circuit using two 555s and a pair of NPN/PNP transistors to drive several LEDs meant to outline a small sign. Designed with my son for a St Patrick's Day project, in KiCAD.

This project demonstrates a simple LED flasher/blinker circuit using a 555 timer IC in astable mode. It's ideal for electronics beginners and includes PCB design files, a schematic, and a bill of ...

This simple Mock Flasher LED simulates the indicator of a sophisticated Alarm system. It can be placed in doors, gates and vehicles to confuse intruders. The circuit is too simple using a Unijunction ...

In this post, two LED blinking circuits are given below. First one is dancing bi-color LEDs (two different color LEDs) where the two color LED will run in sequence. In the second circuit, we will ...
