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.
