Hi Tommie,
The Prop doesn’t directly let you sample analog signals. You can build a simple delta sigma ADC with a capacitor and resistor using 2 Prop pins, or use an external ADC like the MCP3208. Check out tutorial #13 on how to use ViewPort to graph analog values read using such a method- that demo graphs the microphone input on the DemoBoard.
