I'm using Wokwi simulator for 8x8 and now I have a problem. I get last row light up and I don't know what cause the problem. byte character[27][8] = { ... { B11111110,B11000110,B10001100,B00011000,B00110010,B01100110,B11111110,B00000000 } //Z } void DisplayLetter( int n) { for(int j=0;j wokwi.com/projects/381073647771887617
@@its015 Can you please explain why transistor is needed. I'm a beginner. You mean only 1 transistor? or all of the them? Does that mean everything for row must be reversed? For row to be 0, base of transistor must be high or 1?
