Hello - firstly, the electronics part is not really my forte at all and I am waiting for the programming side. I have just made my circuit and ... nothing.
No smoke, no light. I have followed everything (I thought) word for word and I have my battery pack plugged in. I am sitting with a multimeter and I know I have current all the way up to LED and then nothing - just in case I made a temporary connection with an additional LED but still nothing.
Please can somebody tell a noob what to look for?
