A technique for replacing the ATmega328P controller on an Arduino Uno with the older, almost identical ATmega328 model. My main purpose here is to record this information in the cloud where I can find ...

There are many reasons to build your own Arduino circuit on a protoboard or a custom-designed printed circuit board. At the heart of the Arduino platform is an AVR microcontroller, in usual way you ...

Anyone who enjoys building electronic projects using the Arduino prototyping and would like to program their own Atmega328-PU chips. May be interested in a new Arduino prototyping kit and bootloader ...

This repository contains a customized version of the Arduino bootloader firmware with watchdog timer (WDT) support. The stock Arduino bootloader introduces a couple of seconds of delay during boot in ...

Since you lacked the USB interface in your own Arduino board, it becomes necessary to use a homemade/ready-made USB to Serial Converter Module as an efficient and economical solution. Inexpensive and ...

I’ve been using the Arduino Uno board for quite some time, and I’ve always wondered what it would take to get the ATmega328P (the original chip used on the older Uno boards) working completely on its ...
