+I used the "Grove RGB LCD Display" by Chandler Matz
+https://developer.mbed.org/users/cmatz3/notebook/grove-rgb-lcd-display/
+as a platform to create a remote control with display for a
+10hp up-cut saw that cuts aluminum, plastic and other materials. It is 
+controlled by a Variable Frequency Drive (VFD) which is mounted at the 
+back of the saw, making it inconvienient to change the blade speed 
+to match the material being cut.
+****USED****
+Board = FRDM-K22F 
+Pot = 50K multi-turn
+VFD = Leasson Speedmaster series
+Analog input over pot from control 0-10V (T2, T5)
+Analog output from terminal (T30) 0-10V
+3 x 3.3K ohm resistors
+1 x 6.2K ohm  
+2 of the 3.3k are pull ups for I2C and the other is in series with 
+6.2K from T30 for ain max of 1mA @ 10V = 3.47V (this came out to be very 
+close to the K22 supply from the FRDM board)
