I might have bricked my ATmega168a and possible an ATTiny or 2. Lets call these lessons learned. From this post https://www.avrfreaks.net/forum/tutsoft-recovering-locked-out-avr, which is a bit over-my-head, there is a 90% chance I can rescue my AVRs. If I understand correctly, I can use my Dragon over HVSP to reset the fuses, which I think may be the issue. Now for the question; My 168 is on a breadboard; does the 168 require an external crystal with caps?
