This is a novel flasher circuit using a single driver transistor that takes its flash-rate from a flashing LED. The flasher in the photo is 3mm. An ordinary LED will not work. The flash rate cannot be altered by the brightness of the high-bright white LED can be adjusted by altering the 1k resistor across the 100u electrolytic to ...
Nettet5. apr. 2024 · LED Flasher Circuit Diagram. The circuit diagram of the 5-color flasher is shown in Fig. 2. The circuit comprises a 12V battery (or 12V adaptor), timer IC 555 (IC1), decade counter IC 4017 (IC2), five BC548 transistors (T1 through T5), five sets of 5mm red, green, blue, white, and yellow LEDs each, and a few other components.

NettetThe two circuits below are typical connections. In the first circuit a flasher circuit in series with a 220 ohm resistor turns on a power transistor. In the second circuit, a power FET is used in place of the NPN. A pull-down resistor is added to pull the gate low when the circuit turns off. Don't hesitate to modify this basic circuit to meet ... NettetStep 6. Now connect a 220R resistor with the LED -ve and thus the Transistor's Emitter Pin as shown within the image. Here you've to supply 3V to 5V supply. In my case, I even have used a 3.7v 18650 LI-Ion Battery. Here you will see the LED is Flashing.
