Fast blinking LED bike light circuit Posted: 05 Mar 2016 12:39 AM PST This is a fast blinking LED bike light circuit For safety when the bike at night. We use two-NPN-PNP transistor oscillator circuit and RC circuit only show on 4 LEDs use low current. We take the four LEDs to parallel because each LED use voltage about 3 – 4.5V We want this circuit for long time using so use the LED voltage is 3V only. And makes them to blinking as the LED flasher. Figure 1 Testing the LEDs in parallel. They use current about 0.077A. But we use them in switching so low Figure 2 the circuit diagram of Fast blinking LED bike light How this circuit works This is simple transistor oscillator circuit as flip-flop. We use a The post Fast blinking LED bike light circuit appeared first on Electronic projects circuits.
