<<<< Previous : One Seven Segment Display + 7490 + 4511 + Arduino Mega
In the last blog, we saw the circuit to control a common cathode seven segment display using an arduino mega, a 7490 and a 4511. Here, we will design a circuit to control two common cathode seven segment displays using an arduino mega, a 7490 IC and two 4511 ICs. Circuit is done as shown in the following diagram.

Complete the circuit. Ground terminal of external voltage source and ground pin of arduino should be interconnected. Otherwise, circuit will not work. Read the remaining part in next page.

Great project, but why do you not multiplex the led 7 segment displays ?It would limit the number of 4511 chips to one and add a tranzistor for each 7 segment display.Code would also need to chamge though.
