Hello.
I have just assembled this kit.

One of the segment in the display i missing , there are no supply to the resistor for the segment.I have also checked the printed circuit .

I cannot change the code, nothing is happen when i enter the s mode.

Help me please

Remove µcontroller from its socket. Check if the pin that drives the ‘missing’ segment is not shorted to ground. Next, check if µcontroller drives the pin correctly.

If all else works when rotating the button, then you make a mistake while changing the code.
