As I say in the video, during one of my project I had some trubles burning a bootloader to one ATmega328p AU microchips. The difference between AU and PU is their SMD or DIP formats. I found on internet how to burn the arduino bootloader using an Arduino UNO but after doing that my microcontroller wasn't working ok. It had frequency problems and I only could program it selecting an Arduino UNO board in the arduinio IDE. But since I am using an ATmega328p AU which is the microchip that the Arduino NANO or pro mini uses I tried burning the bootloader using an arduino NANO and everything worked ok since then.

Please download the schematics before you start and have them in front of you.

Steps: First take one Arduino NANO and upload to it the Arduino ISP example code that you can find in File-Examples-Arduino ISP. Once you have uploaded the code to the Arduin o NANO make the conections that you see ion the Arduino NANO to the ATmega328p AU chip conection. Once you've made the connections go to the Arduinio IDE again. Go to Tools-Programmer and select Arduino as ISP. Finnaly go to Tools again and click burn bootloader. it's done! You've burned a bootloader to you new SMD microchip. To upload code use the RX or TX pin of an Arduino or use an FTDI module!
