This one is really useful.

Most of the times you are developing a project, you will need some sort of monitoring or visual output to understand the status of your program. Sure some LEDs blinking are great but some times you need more. This is where the good old serial communication comes in. Through this communication you will be able to send information in the form of data or text, to and from your computer. You can use it as a debugging tool to monitor what is going on in your microcontroller during execution time. Or you can use this communication to send data to the PIC for processing and then receive the result back. I am sure you will appreciate the usefulness of this as soon as you implement it.

And all this happens by sending a sequence of zeros and ones… Continue Reading
