			The next step was to unsolder the ATMEGA328P and solder in a new one to program. Sockets for these are expensive, and even if we had the budget, there is no time for any other method.

===Bootloader Programming===
The bootloader is a program that needs to be loaded into the ATMEGA328P before you can program your Arduino with the USB/serial programmer.

We really should have provided a programming header for that as well as the one for the USB/serial programmer, but since we didn't, the professor will program your ATMEGA328P units using the information on [http://angryelectron.com/how-to-update-the-bootloader-on-arduino-pro-mini-328/ this web page].

I read the original firmware into an Intel hex file using this command below just in case the ATmegaBOOT_168_atmega328_pro_8MHz.hex file doesn't work.

Now I programmed the ATMEGA328 using the following command: Don't do this! It turned out to be a good thing I backed up the original firmware, because though the following programmed okay, I couldn't use the serial programmer to load sketches from the Arduino IDE.
<nowiki>

So after testing and finding this bootloader wouldn't allow programming sketches from the Arduino IDE, I flashed back the original firmware, and it worked.
