Schließ mal AVcc an Vcc an, der portc wird sonst nicht richtig versorgt.
Und die 100nF an dem pin nicht vergessen.
AVCC AVCC is the supply voltage pin for the A/D Converter, PC3:0, and ADC7:6. It should be externally connected to VCC, even if the ADC is not used. If the ADC is used, it should be connected to VCC through a low-pass filter. Note that PC6...4 use digital supply voltage, VCC.
