I wanted to test my code and came to the point where I wanted to read the Analog In Channel 1 in mA mode.
Unfortunately the sketch seems to hang at Indio.analogRead(...).
Do I need to connect a power supply for that? I currently only have my USB attached to program on the table...
Same for expansion port, I wanted to connect a DS18B20 and use 5V/GND of the port + D7 as data line. But also there it seems no 5V available if only USB is plugged in.
Can somebody confirm/give advice?
