Starting with hardware, the Arduino Mega is based on the Atmega2560 microcontroller. In the iteration that is found on the Mega board, the microcontroller comes in a standard TQFP 100-pin package.

Sure, the physical build itself looks great, but it’s what [Michael] did with the firmware that impresses us the most. He’s using an Arduino Mega to drive the 7x7x7 cube and manages to squeeze out ...

There are easy ways of getting more I/O pins for any project; shift registers, I2C expanders, or ADCs will give you plenty of pins for whatever project you have in mind. All these require extra ...

Having had such quick success making a microcontroller project using an 8pin ATtiny85 and programming it with Arduino, I though I would try a more elaborate project, one that has been on the back ...

This comprehensive guide covers everything you need to know about Arduino, a project to ease people into creating their own DIY gadgets and electronic art. If you’ve ever had a hankering to make your ...

Arduino is so much about what is made with Arduino boards that we hardly spare a thought for the boards themselves. Well, Arduino cares, and they've just gone about redesigning their base model, now ...
