simple 15v powered led flasher circuit


Posted on Feb 5, 2014

This is a simple 1. 5V powered LED Flasher circuit diagram. This circuit can flash 1. 7V or 2. 3V LED (depend on the color) using 1. 5Vdc input. The LED will turn on when the 100u capacitor jacked up  by the collector of BC557. The circuit is a charge-pump design. This is where a capacitor (electrolytic) is allowed to charge and is then raised highe
