i played around with the 74HC595 today and followed the playground tutorial regarding this piece of hardware.
The problem is that non of my leds are willing wo light up. I tripple checked the wireup and im sure this is not the problem.
I can measure voltage on the output pins of the 74HC595. Here is a foto of the setup:
After hours of searching i loaded up the blink sketch ( pin13 high/low ) and wired up an led with a 220ohm resistor to it.
The funny thing now is that even that LED is not willing to light up. I check that the anode is in the right direction.
So i tried something even more basic:
I wired the resistor and the led to the 5V output of the arduino and wired the cathode to a ground pin.
Could it be that i somehow fried my arduino ?
What should be my next steps ?
