 \subsubsection{Potentiometer}
 The \textbf{blue} wire from the potentiometer to the main control box is the signal wire, on connection 7 in that box.

 \subsubsection{Motor control}
 We bought BC547 NPN transistors to control the 12V/20mA (\href{http://download.lenze.com/TD/8201-8204__Inverter__v02-08__EN.pdf }{docs}, page 4-11) or 14V/40mA (measured) current of the EVF8202-E frequency inverter, and also base resistors otherwise the Arduino needs to give too much current to the transistor, and the transistor will be slow to turn off because of 'base charge storage'.
