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.

In this series of videos, [Jack] will explore how to program for the ATmega328p processor using C. If you have been programming for the Arduino, you may have had some issues with the speed of your ...

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.

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 ...

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 ...

The Arduino Uno R4 is to have a Renesas RA4M1 32-bit Arm Cortex-M4 microcontroller, and there are “no plans to discontinue the popular Uno R3” , according to Arduino, which estimates that R4 will ...

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 ...
