Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

[Andy] stuffed some more RAM onto an Arduino Mega and his three-part walk through on the design, construction, and software is a great read and one of the more ‘hard core’ Arduino builds we’ve seen.

I am working with arduino mega 2560, arducam rev c+ shield and OV2640 camera. I attached both together by stacking right on top each other, with reference to arduino mega pin 8 to arducam pin 8 as ...

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.

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 ...
