Led Flasher Using Bc547 And Bc557 Transistors This circuit uses a bc557 pnp transistor connected to a bc547 npn transistor in such a way so that the bc547 conducts for a very brief time making the led light. the resistor r, and capacitor c, determines the timing of the flasher, and the period is proportional to r × c. the capacitor c charges through the resistor r, and since its value is.
