4 leds

1 74ls163 IC

1 4 Pack Dip Switch

1 9V Power Source

This circuit is used for counting up or down in binary. It also has the capability to start counting from programmed number.

1. Dip Switch- connect all four pins of one side to VCC+ The remaining four pins will connect to inputs QA-QD of the 74ls163
2. 74ls163 - connect the QA-QD output pins to the leds. Example: QA - positive led 1, QB - positive led 2, so on and so forth. (Pin 8: Ground Pin 16: Power Pin 1, 7, 10: Power) Pin 2: Clock (555 timer)
3. In Multisim I used a digital clock for the pulse. Pin CLK
