@asandford, @Douglas6: Yes, AREF is 5v [1]. I guess there's nothing to do now, right?

[I2C] Troubles with an Arduino connection

I'm trying to connect a RPi to my Arduino Leonardo. It worked the first time but now it's not working anymore, plus, `i2cdetect' returns a weird output (see below). Here are the steps I've done: 1. Wiring SDA an SCL pins from the RPi (pins 3,5) to Arduino's SDA and SCL. 2. Wiring GND from the RPi (p...

I have done something similar using udev rules (although not generated a configurable tool to do it), where my Pi shuts down if I plug in a specific memory stick (an old 128MB one, that is too small to be any use now). Thanks for reply rpdom. Catching the 'Add Device' action is...

Safe shutdown by unplugging a specific USB device.

Hi everybody, this is my first post here. I want to show you an idea, hope to read your feedbacks. Basically, it consists in a tool that lets you safely shutdown a RP by unplugging a specific USB device. It comes handy to avoid hard-shutdown by unplugging power supply when you use a headless RP-base...
