Transistor Flasher Circuit Diagram

Which it has highlights is there are two types of transistor are npn and pnp.

Transistor flasher circuit diagram.

Both npn transistor you can use of bc547 548 or 2n2222. This circuit can be operated using dc 6 12v supply. The two circuits below are typical connections. And instead of led how can i connect transistor which can act as a switch the transistor switch will be on for 1sec and off for 1sec 2 the circuit diagram is shown in the link below.

We can create a dancing led circuit by combining many similar circuits which we can use for advertisement boards. The flash rate can be adjusted by changing the value of 1k resistor used in the circuit. This circuit basically works on the charging and discharging of capacitors. In the first circuit a flasher circuit in series with a 220 ohm resistor turns on a power transistor.

Can be used on roads for signaling purposes. In the second circuit a power fet is used in place of the npn. Power transistors may be added for handling higher current loads. Here is a one transistor led flasher circuit which will flash a super bright led.

Circuit diagram blinking led circuit. The transistors do not necessarily have to be bc547 you may use 2n2222 or similar small signal transistors but it is recommended to always use the equivalent transistors. 1 in above circuit can the blinker time be adjusted like on for 1sec and off for 1 sec. This led flasher circuit is very easy and simple and there is no ic used.

It can work as well as the use of ic 555 or other transistor circuits. Use 9v or 12v battery or adaptor for this circuit. The circuit is using 2n3904.
