P1AM

P1-04ADL-2

Voltage Input

This module can read the 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 inputVolts = 10 * ((float)inputCounts / 8191); //converts the value of inputCounts to float with the units V
digitalReading = base[1][2].value   #store the digital value of slot 1 channel 2
                    analogReading = base[1][2].real  #store the analog value of slot 1 channel 2 with the units V
