This circuit demonstrates inner workings of the 555 timer IC. It is possible to adjust both TRIGGER and THRESHOLD pin input voltage independently. A push button connected to RESET allows its independent activation, too. Switching of internal discharge transistor is indicated by a red LED attached to DISCHARGE pin. Voltage at the OUTPUT is indicated by a green LED attached to it.
