Introduction to ADCs on PIC using MPLab and PIC18F4431

People often ask me about how to wire up a PIC to configure it to read Analog data and convert them to serial. Though its very easy to set it up – it gets rather frustrating if the same question is asked multiple times in a week – the remedy? A tutorial of course! And what best way to do a PIC tutorial by using the free MPLab integrated development environment (IDE).

This tutorial uses the PIC18F4431 to demonstrate how to use the PIC’s ADC and use the obtained data in pulse width modulation (PWM) to drive a LED – greater analog input corresponds to a brighter LED while the lower inputs would result to dimmer LED output – talk about getting visual. The tutorial is complete with instructions, schematic diagram, project files and even a breadboard layout! So what ya waiting for? Do the grove and start to move!
