Arduino IDE on 64 bit Ubuntu Gutsy and HardyArduino is an open-source electronics prototyping platform. It is a chip you can program, connect sensors, motors and leds. I describe how I successfully installed and run Arduino IDE on 64 bit Ubuntu Gutsy and Hardy. I did not compile any Arduino code and I did not connect an actual Arduino chip to computer. I later used this setup to develop machines using the Arduino chip and it worked fine.
