i had posted this on the wrong thread earlier so forgive me if this turns out to be a duplicate.
I just got my SMD board fabricated to test it. i solder all the components using a hot plate.
Earlier all worked properly on a through hole with DIP package Atmega but when my Arduino on the standalone SMD board is booted PIN 13 goes LOW or at least that is how i understand (i maybe wrong)
Normally the pin called buttonPin on PIN 13 of the Atmega328 TQFP32 enters a menu once held down for 2 seconds. So i guess this is something that is happening once it is booted I checked the continuity and there is no short to GND.
Would somebody please help me troubleshoot this. I probed Pin13 and i just see a 1KHz frequency from the buzzer interfering but would that be a problem ? is it because the buzzer PIN 11 is close to pin 13 ? I uploaded another sketch and that had no problem with buzzer and ButtonPin as is.
