Eight LED`s are used to indicate the pad currently selected. These LED`s are connected to a decade counter, which sequences the LED`s when it receives a clock p...
Voltage Controlled Switch with 555 – Circuit Schematic
Voltage Controlled Switch with 555
The old and omnipresent NE555 can be very good at something it was not meant for: driving relays or other loads up to 200 mA. The picture shows an example circu...
