Demonstrates analog input by reading an analog sensor and turning on and off a light emitting diode (LED) at a rate determined by the analog sensor reading.
This tutorial shows you how to use the DebugSerial function over the USB port of your UP²* board. The DebugSerial function will only work if your UP² board is connected 'via Cloud'. If you are connected via micro USB cable, then see this Serial tutorial.
In this example you’ll learn how to make system calls from Arduino* sketches.
