Hi, I started a couple topics abut this subject. After some research managed to get it working using this method:
Now my question is: how many serialized displays can I have?
The 2 possible issues that come to my mind are:
1- Is current a problem? As far as i understand only 1 segment/digits is lighted at time, so it wouldn't be a problem, am I wrong?
2- What about Light intensity? With the example above the 4 digits seem to have the same light intensity, will this change if I add more displays?
Well, these are my doubts right now. Thanks in advance.
