This means that there is still a\u003cstrong\u003e 5-second\u003c\/strong\u003e \u003cstrong\u003edelay \u003c\/strong\u003efrom when you press the reset button to when the Arduino runs the sketch but that after you upload a new sketch it will begin immediately. This makes the debugging process much faster!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBe sure to select \"DUEMILANOVE with ATMEGA328\" in the Arduino IDE\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHowever it means that when Processing (or MaxMSP) opens the serial port, on an auto-reset Arduino there is a 5 second delay until the program starts. Which is why they added a second modification: If the first character sent to the Arduino isn't a '0' (ASCII zero, hex value 0x30) then it will automatically start the App. Bootloading works just fine but if you are talking to the Arduino with other software, just write a character to the Arduino that isn't a zero after opening the serial port to skip the long delay.\u003c\/p\u003e\n\u003cp\u003eOther than that it works just like the 'standard' bootloader, at \u003cstrong\u003e57600 baud rate\u003c\/strong\u003e for speedy uploading.\u003c\/p\u003e\n\u003cp\u003eIt will work in any NG, Diecimila, Duemilanove, UNO and Freeduino\/Clone Arduinos as well, and will auto-reset when used with version 009 of the IDE software, or later.\u003c\/p\u003e\n\u003cp\u003eFor easy upgrade instructions, see the instructional webpage.
