ATXMEGA32A4U ADC periodic noise
Don’t waste your time. The problems can’t be fixed by cutting tracks and adding bits of wire. Get the design right first. Getting pcbs made is fairly cheap. Having components on...

Duplicating eeproms
I’d contend that sufficient electricity would erase it - permanently.

ATXMEGA32A4U ADC periodic noise
We’ve got nowhere near enough information. If you want to learn, there’s plenty of tutorials on line. It helps if you understand basic electronics as the pcb is a critical...

Best if you draw schematic so we can be sure we understand.   On data, use a RC filter and a tvs diode. TVS diode has capacitance - choose carefully.

How to convert a decimal number in a register into an ascii format?
Sounds like you wanted binary to bcd. Mentioning hex just confuses the issue. There’s two common algorithms - divide by descending powers of 10 or a modified division that...

ATXMEGA32A4U ADC periodic noise
I’d throw that pcb in the bin. The power routing is suspect at best. It could be the regulator oscillating occasionally. Showing us a small part of the pcb is not going to be too...

Fully DIY Radio Transceiver System - Thoughts?
Receiving just about anything is harder than transmitting it (except for money - i’ll happily accept donations!). With RF, the signal might have a dynamic range of 1000000:1. With...

Consider the voltage drop across the 0V wire due to current. Also consider EMI and ESD. You need protection and filtering. Your transistors look much nicer. Do the same to P1 and 2

eRony - How many commercial devices have you seen that use microcontrollers and motors? Do they use opto isolators? Probably not. Optos aren't quite the magic cure you think...
