not being an E. engineer I’m not going to say something is wrong, but it appears capacitor C9 in the sample file (breadboard view) is flipped the wrong way, can someone verify this for me? Also, the wire on pin 21 (AREF) to the positive rail on the ATMEGA328 is troubling me. In several other breadboard examples (online) it is not there is this incorrect also? or perhaps optional? being just a hobbyist I cant be sure and with Digikey selling me all there non-working crap (I.C’s, PIC’s, crystals…) I have yet to get this circuit working properly.I Replaced ATMEGA328 from Digikey with Mouser’s and bootloaded just fine, Digikeys did not. All that remains to check/ (replace with Mouser parts) is the crystal and 22pf capacitors. this circuit seems to have a very generic setup across the board but mine doesn’t work. Faulty diagrams and faulty parts are all that’s left unchecked that’s why I’m here, to eliminate the faulty diagram, can anyone help? Thanks in advance for any responses.
