The keypad uses an onboard ATMega328P to scan the matrix for button presses, decode them, and send them via UART or I²C to an Arduino.

The PCB Martin has designed takes the form of a small but versatile PCB based on Atmega328P Arduino Pro Mini board, check out the video below to learn more. If you liked this you might also be ...

This week we continue on with another video in our series about how to program for the ATmega328p processor using C. The ATmega328p is at the heart of many Arduino boards. If you have been using th… ...

If you would like to build your very own binary watch you might be interested in a new project published to the Instructables website by member Taifur.

I had cause to have a closer look at some Arduino inputs – it is that fascinating weather station again. It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than ...

Writing code for an Arduino-friendly board is relatively easy; creating the board is the hard part, unless you live and breathe electrical engineering. If HackEDA has its way, however, the design ...
