The frequency of which is adjustable via the variable resistor. The board has a choice of two outputs. The logic output can be used to drive another IC or a speaker can be connected so the tone is heard (e.g. a door bell).\u003c\/p\u003e\n\u003cp\u003eThe push button switch connects to the reset line
