The project is a simple way of producing a fading LED without the need to program the chips or write the code but rather using a few simple components with a constant fade up and fade down as the end ...

The purpose of building this circuit is to create a LED flasher with alternating sequence from the two LEDs where the operation is based on the functionalities of a 555 timer integrated circuit. 555 – ...

This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main element (see the figure). The timer, IC1, functions as a resettable astable multivibrator where R1, R2, and ...
