    ATtiny: 7-Segment Display

    This circuit uses the ATtiny 8-pin microcontroller which has 5 I/O pins to create a 7-segment display. Since a 7-segment display only requires control of 7 individual LEDs, we use 4 of the ATtiny I/O pins as charlieplexed outputs (n*(n-1)). Leaving the the fifth I/O pin to be used as digital or analog input or another output.

      The link to the code does not currently lead to code. Could you please check the link and share it again. Thanks!

      Never mind, I found the code at this link: https://github.com/plusea/CODE/blob/master/PROJECT CODE/ATtiny Seven Segment/a_tiny7Segment/a_tiny7Segment.ino
