Serial monitor window will show the decimal value change (between 0 to 1023) correspondingly. The potentiometer on IO shield which provides input voltage to analog input A0 of UNO32 board, can be turned to get the varying voltage levels.A new serial monitor window will appear as shown below,.Once the code is done uploading, open the serial monitor from the toolbar shown below,.Unless you type your own code in the sketch, you wouldn’t need to verify them before uploading. This will compile your sketch (check for errors) and then send to the Microcontroller. To load your sketch onto the chipKIT UNO32 board’s Microcontroller, press the upload button.This will depend on which port was assigned to the chipKIT UNO32 Board when first connected. Once connected, in your MPIDE window, select Tools>Board>chipKIT UNO32 to identify the UNO32 Board as the target.

LEDs and A0-potentiometer of the IO shield will be used as peripherals for Uno32 board, in this excercise. Place the IO shield on top of the Uno32 board with a bit of a firm press.Make sure you connect the Uno32 board via the mini-B connector on board to an available port on your computer.Serial.println function, prints in a new line each time the values from sensorValue variable in decimal format. Using analogRead function, enables the chipKIT board to read the input voltage at port A0 ranging from 0 to 3.3 volts into values ranging from 0 to 1023 (as chipKIT board has a 10 bit A/D converter in it). In this case, the baud rate for communication between the computer and the chipKIT board is set to 9600. The function Serial.begin(), sets the data rate in bits per second (baud rate) for serial data transmission. This example code is in the public domain.

Reads an analog input on pin 0, prints the result to the serial monitor

Open MPIDE software on your PC and go to File > Examples > Basics > AnalogReadSerial to open the code which reads the analog signal on serial window.

The reference guide for each board, schematics and other resources are available on their individual homepages: The hardware used in this tutorial will be a chipKIT™ Uno32 along with a chipKIT™ Basic I/O Shield both manufactured by Digilent Inc. Using a potentiometer measuring instrument, you could measure the electric potential. A potentiometer is a three-terminal resistor with a sliding contact that forms an adjustable voltage divider. In this project you will learn to use a basic functionality of chipKIT board, which is to read a analog value and output the corresponding digital reading for it.
