WebJul 25, 2016 · Use current limiting resistors of 470 ohm should to connect the 7 segment pins from IC 4026. I have omitted it in the circuit diagram for simplicity. Use pull down resistors R1 and R2 to maintain pins at ground potential and prevent the chips from short. You can expand this stopwatch to display hours by adding two segments and 4026 more. WebSep 21, 2013 · Make the typical connections for the 4026 IC, like Vcc, ground and 7 segment display pins connections. Invert the output of PIN 9 ( d ) using a NOT gate. The output of the inverter goes to a 2-input AND gate. The second input for the AND gate is from PIN 10 ( a ) without any inversion ( direct connection ).
