1. In the most basic scenario you need 8 data pins to connect 7 segment display to arduino .The pins would control: 7 segments that make a digit an...

2. Shift Registers are sequential logic circuits, capable of storage and transfer of data. They are made up of Flip Flops which are connected in su...

3. Ground of Arduino is connected to GND of Shiftregister as well as to Enable Output pin. Arduino 5V goes to Common pin of 7 segment display and V...

4. Compared to the code I had for the basic 7 segment display connectivity I add a column to the digits table representing decimal point.void Displ...

5. There is a simpler way of displaying digits using shift register.There is a shiftOut command that does all data clock and latch sequencing for u...

6. To create the PCB design I used Fritzing software. It is a free software that you can download. I created the circuit design Fritzing automatica...

7. After receiving the ordered PCB board you can solder all required components onto it.

8. We connect the custom display module to arduino.After powering the arduino you can see the diits are properly displayed in the sequence.If we ad...

9. Now imagine that we have 2 displays and you want to display 16 bit sequence. Through the data pin of the first register we push it into register...

10. Lets write the final piece of code. With two daisychaned modules we would like to count from 00 to 99.The code would look like this:void loop()...
