A sample code for a four-digit common anode display is shown below: #include <SevenSeg.h> SevenSeg disp(11,7,3,5,6,10,2); const int numOfDigits=4; int digitPins[numOfDigits]={12,9,8,13}; void setup() { disp.setDigitPins(numOfDigits, digitPins); } void loop() { disp.wri...
Don't forget that the display uses LEDs, so you should use current-limiting resistors in series with thedigit pins. 330 ohms is a safe value if you're unsure. If you use current-limiting resistors on thesegment pinsinstead, then set resistorsOnSegments to true (see the example SevSeg_Coun...

If you need a fast and easy way to add some user input and output to a project, these display modules are interesting and fun. They contain eight 7-segment red LED digits, eight red/green LEDs and also eight buttons for user input. The units can also be
Step2 : Please have a look at the pin diagram of 7 segment display – 4 digit (This is specific to the model i have mentioned above) Really hard to find these details in net. Now make the circuit as below Note : Digit Pins
