This circuit be Basic Timer Circuit by use important equipment is FET2N3819. By this circuit can can delay long ago arrive at 1.5 minute. Stand S1 at a position Reset an electric bell will loud. Totter S1 come back at time an electric bell will silent until time drag will stop electric bell talk at one time again. If friends enhance the value C1 or R1 for delay long ago go up. devalue R2 while stay in a position Reset for Reset fast go up. Request friends have fun Basic Timer Circuit , please sir.
