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 ...

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 ...

While newer Arduinos and Arduino compatibles (including the Hackaday.io Trinket Pro. Superliminal Advertising!) either have a chip capable of USB or rely on a V-USB implementation, the old fogies of ...

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 ...

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 ...

twiboot is a simple/small bootloader for AVR MCUs written in C. It uses the integrated TWI or USI peripheral of the controller to implement a I2C slave. It was originally created to update I2C ...

If you’re new to the world of Arduino, here’s what you need to know about the ATmega328P before using the board: 1. The ATmega328P is a powerful chip The ATmega328P is based on the AVR architecture, ...
