In this tutorial we will see how to read the ADC values on PIC16f877A starter board.<br>
Starter board comes with on board POT connected to ADC0, same POT value will be read and transmitted on UART at 9600 baudrate.

=PIC16F877A ADC pins=
PIC16F877A has inbuilt 8channel 10-bit ADC. Below tables shows the ADC pin mapping.<br>

=Code=
Below is the sample code to read the ADC value of channel0 and sent it on UART at 9600 baud rate.<br>
As the POT is connected to ADC0, the values can be varied using this POT.
