    tester circuit
    the operation of the Ic tester is follows:
    *wait until the push-button switch is pressed
    *when the push-button is pressed, debounce the switches contacts by delaying to read swicth output
    *Send a logic 0 0
    0 1
    1 0
    1 1
    to gate inputs
    *read gate outputs 1
    0
    0
    0
    *read gate outputs . if all the gate outputs are right , assume that the gate is working and turn ON the green led
    otherwise assume that the chip is faulty and turn On the red led
