Hi,
I'm new to microcontrollers and I'm trying to build this 4x4 LED cube, controlled by an Atmega16:
https://www.instructables.com/id/LED-Cube-4x4x4/
I've completed the circuit as shown in the tutorial and am testing the output pins before I put together the rest of the cube.
When I set the pins PC0-PC7 to high, I measure 5V at each of the pins except for PC4, which is always 0V. I've taken a look at my soldering and it all seems fine. Is there any obvious reason I'm unable to set PC4 to 5V?
