It will only provide power to the Arduino on the positive half-cycles of the AC waveform.
I would like to use my Arduino Uno with my 3Com AC Adapter.Here are its specs:OUTPUT: +12.0V 1.25A
Thank's I wasn't sure about the voltage (12V is pretty high for the Arduino, isn't it ?) and the amperage.
And isn't it bad for the Arduino to be powered at its voltage limit all the time ?Is it better to find a 7V adapter ?Edit: Ok, I tried a few minutes but my Arduino became pretty hot...
