By using IC NE555, which causes wave clear the sector output allows the voltage nearly 6V after the signify on the output from a pulse plus C2 acts charge through D1 to ground and if the pulse harmful capacitor C2 desire discharge. through diode D1 and capacitor C3 to chage so as to negative voltage is about-6V, but being aloof to the run to of absent-5V zener diode ZD1 current output will happen approximately 12mA. To test the circuit or else circuits with the purpose of may well need various circuits, but we take refusal fire-5V power supply-5V, but if the battery 9V circuit can allow us to avail yourself of the volt-5V being desired.
