This Arduino Mega sketch uses direct port read and bit manipulations to sniff an i2c bus running at up to 100 kHz. The analysis of the i2c communication is displayed on the Serial monitor. Connect SDA ...

The Arduino Team presented some new products at Maker Faire this weekend. It’s a significant update. The Arduino UNO and Arduino Mega 2560 update the Duemilanove and Mega respectively. They now use an ...

Arduino enables the fast development of embedded projects. Playing around with Arduino boards is fun, but not the most efficient way to expand your knowledge. Elektor has therefore bundled two of the ...

The Z80 is one of those old CPUs that is both obtainable and easy to work with — at least in some versions. [Doctor Volt] put together what may be the simplest possible setups to get a working Z80 ...

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 ...

Chuck Todd has built a Arduino compatible Mega2560 expansion RAM that will enable those using the Arduino platform who need more that 8k RAM in the Arduino processor. Originally Todd created a ...
