I bought a 4 digit seven segment display a few weeks ago and I tried to use it today with my Arduino Due but it did not turn on any of the segments. I have used it previously and it worked just fine. I tried changing code and did what I could think of but nothing worked. How do I check the SSD itself to see if it works or not?
Hi kkukula.
What display are you using? Also, when you originally tested it did you use a Due or a different board? What happens if you use an Arduino Uno and our sample code?
