I’ve been trying to program my ATTiny45:s for hours. No luck. I tried every guide I found.
Crystals, caps and tons of foul language later I pull out the wires one more time and start all over again. This time my third hand with magnifying glass is out on the desk. I don’t use it for breadboarding, but it’s there this time. I suddenly see a glimpse of the ATTiny45 chip and get impressed how clearly I can read the text: ATTINY85. Wait, what?! 85? I immediately try to upload the blink sketch and voila! IT WORKS!
Turns out my order must have been mixed up somehow. I ordered a small bunch of 45:ers, but got 85:ers instead. I even went and double checked just to be sure. When I got them I never really bothered to read them. I just lined up the chip and started tinkering.
One more mistake to tick off the list as a beginner! And one more lesson learned. Woohoo! :OD
