An LED chaser, also called as sequenter is one of the most common LED controlling circuit. This post presents circuit of the 3 LED chaser. The LEDs blinks one by one and the process repeats which gives the running light effect. Circuit is based on BC547 transistors.
|1.||Power supply (3V – 5V)||1|
|4.||100μF electrolytic capacitor||3|
The speed of the LED chaser is affected by values of C1, C2, and C3 capacitors.
Circuit is designed on a breadboard.
