Verify Output
Build and program the example project and reset the device. The LCD shows the voltage reading
corresponding to the voltage on the potentiometer.
you turn the potentiometer, the voltage value changes. You can also verify the voltage on the
potentiometer using a precision multimeter.
Note The potentiometer connects to a differential ADC, which works in single-ended mode. This
means the ADC input is measured against internal Vssa. Any offset in the measurement can be
positive or negative. This can result in a small offset voltage, even when the potentiometer is zero.

Project Description
This example code uses a pulse width modulator (PWM) to illuminate an LED. When the pulse width
of the PWM varies, the LED brightness changes. By continuously varying the pulse width of the
PWM, the example code makes an LED go from low brightness to a high brightness and back.
Hardware Connections
No hardware connections are required for this project, because all the connections are hard wired to
specific pins on the board.
