CMN fan control
Controlling 4 fans by temperature input from 4 Dallas Temperature sensors. The are one 16x2 LCD display for showing information and errors. The are one pot for setting the fan speeds when the control are in manual mode.
There also three buttons where the first sets the control in low or high speed mode. The next is to toggle between the 4 different fan modules that consists of one sensor and a fan. The last button is for toggling between man or auto mode.
This was an Christmas present to my friend Simon. He half to make the auto mode by him self but there are a lot prepared in the code.
