8-bit binary counter KIT, 5V DC

Schematic diagram

The circuit simply and visually shows how the binary counter works, we can observe the way of counting up on the LEDs. The counting speed can be adjusted using a potentiometer. Power supply: 5V DC Maximum current consumption: 18mA The set contains parts to be soldered! Add to basket (Part no.: 100.467.69) 1+: 691 Ft 5+: 511 Ft 10+: 482 Ft 20+: 463 Ft 50+: 445 Ft

The supply voltage must be connected to the (+) and (-) points marked on the circuit. The polarity and actual voltage of the power supply must always be carefully checked before connecting to the circuit.
(+) = Positive supply voltage pole (usually red)
(-) = Negative supply voltage pole (usually black)

After wiring the 5V supply voltage with correct polarity, the circuit immediately ready to use.
