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 ...

SEGGER has released the Flasher Deployer, a new cross-platform GUI utility that streamlines the creation, deployment, and management of a Flasher Setup Package across multiple Flashers. The utility is ...

The circuit is very simple: an ultra-bright green LED, two 10-MΩ resistors, two 100-nF ceramic capacitors and a push-button switch. When you press the button, there is a clearly visible flash of light ...

One circuit diagram shows a particularly simple LED flasher for AC power operation with six channels. All six LEDs flash entirely at random (not synchronised), producing a totally chaotic display.

This is a small size led flasher built with the 555 timer IC that is powered from 2 x 1.5V batteries. The circuit can be used as a flashing metronome, dark room timer, memo-reminder or other similar ...

An LED is commonly used as a "power on" indicator for many electronic devices. For the LED to produce discernible visible light in daylight, the forward-bias current needs to be in the moderate range ...
