So I started building the 50$ robot and I'm in the beginning, where it says I should modify the servos. So, I read the servo modifying tutorial but I was confused by the part where it said I should upload the .hex file to the microcontroller. I think I need to build the board first, right? I checked the posts here and there was no answer I could understand, maybe because I'm not a native English speaker. So, am I supposed to do the electronics first or am I missing something? Also, I can't order things from radioshack because they don't ship to my country, is this board good for the job:
