I wish to display the numbers "1,2,3, and 4" on 2 - 2 digit Seven Segment Displays (SSDs) (CL3621AH Common Cathode). "1" on SSD_1, "2" on SSD_2, etc. When I run my code, the output is "1" on SSD_1, "2" on SSD_2, "1" on SSD_3, and "4" on SSD_4. If I change the first line in the void Loop function to…

You might give this a try. for (int t = 0; t < 20; t++) { // Change max value of t to speed up or slow down the amount of time between number progression shiftOut(dataPin, clockPin, LSBFIRST, bits1); // send data shiftOut(dataPin, clockPin, LSBFIRST, bits3); // send data digitalWrit…
