Having recently starting to teach myself AVR microcontroller development without the comfort zone offered by the Arduino, one problem that really gets on my nerves as an absolute beginner is trying to calculate the UBRR (USART Baud Rate Register) value for a given baud rate and crystal/resonator speed when using the USART communications functionality of the AVR.

Enter  WormFood’s AVR Baud Rate Calculator. This site has been mentioned on blogs before, but it’s so useful that I’d be mad not to mention it here as well!
