Building a Diavolino

On Saturday I picked up an Evil Mad Scientists Arduino clone, The Diavolino, from MadLab‘s little shop “Invent-ory” to use with my RS485 stuff. the Diavolino requires assembly yourself (official instructions).

You can now download the drivers from or PL2303 MacOSX-10.6 up v1.5.1

Install the drivers by following the instructions in the zip, reboot the computer, and plug in the FTDI board (copy wiring from above). load the Arduino IDE and select the board and serial
