ofArduino / first step -> no connection

Hi there,

What are the most known reasons an arduino can connect with Arduino programm, but can not connect with ofArduino (Config. Windows7, Arduino Mega2560) ?

You need to pass a baudrate as an argument when connecting


you can also check which com port your board is connected to via the Device Manager, depending on the board you will also find the baudrate changes, on a new UNO its 57600
