Assume that you need to log some of your readings from the input pins of your Arduino Uno (or MEGA, etc.) dev board which needs to work standalone. The proper way is to store the log in an SD card ...

GND - GND (pin 14 on the ATtiny1641). A4 - SDA (pin 8 on the ATtiny1641). A5 - SCL (pin 9 on the ATtiny1641). You can go ahead and try this with the example Arduino interface script provided. Regular ...

A maker developer has squeezed an Arduino onto an SD card. He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based ...
