<<<<  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.

IMPORTANT NOTICE

All the circuits, published in this blog is only after testing and getting proper results in my private lab. When you try these circuits, you should check the supply voltage, polarity of components, presence of childrens nearby and shorts in the circuits. This website will not be responsible for any harm happened to you or your components caused by your carelessness.
