how to differentiate seven segment displays?
Can anyone tell me how to test whether a certain seven segment display is a common cathode or a common anode display?
Thanks M.L for the information:) sorry i cant rate ur answer cause im still level 1 xD
Unfortunately, externally, they look identical.
The best way to tell the difference is to look at the number on the side or back of the display.
Common Cathodes will usually start with "CC" or "SC".
Common Anodes will usually start with "CA" or "SA".
