looks like I will need some more help.
I connected nanode using FTDI to USB.
When selecting OpenSprinkler as board sketch compiles but on upload I am getting the error: Could not find USB device 0x1781/0xc9f.
Is it possible to upload the sketch to nanoderf using FTDI or I would need to use Arduino as ISP programmer to upload the sketch as in this case http://arduino.cc/en/Tutorial/ArduinoISP
And how do I upload regular Arduino UNO bootloader back ?
