im connecting rpi ardunio pro micro board via serial tx/rx pins. first time im building circuits im little unsure volts , resistors , stuff. i following picture example http://blog.oscarliang.net/ctt/uploads/2013/05/arduino-raspberry-pi-serial-connect-schematics.jpg resistor set ardunio uno , not pro micro. people keep talking plugging in usb or not. im not connecting 3.3v or 5v gpio pins pi , power usb on ardunio , pi micro usb power socket. so want clarify before fry boards resistors , circuits in picture still work on ardunio pro micro (moving pins correct place on board) since arduino pro micro operates @ voltage level of 5v uno, it's serial connection uses 5v. means voltage divider circuit shown in link works pro micro. if want can math on own: vout = (r2/(r1+r2)) * vin vout input voltage @ rx pin of rpi vin output voltage of arduino @ tx pin r1 resistor near arduinos tx pin (1600 ohm) r2 resistor near rpis rx pin (3300 ohm) i hope helps :)
