This module can read the current or voltage of four different input signals.
int inputCounts = P1.readAnalog(1, 2); //set the value of slot 1 channel 2 returned by the readAnalog function to the variable inputCounts
float inputAmps = 20 * ((float)inputCounts / 65535); //converts the value of inputCounts to float with the units mA
