eureka!! now we have wireless communication between our farm and our computer:) as you see in the picture it all looks a bit messy but the hardware is all there and it’s working. so what do we have here? a old computer power supply, one arduino, one xbee, one lillypad xbee board, one refarm board, one old car water pump and two gold water sensors. yep, that’s right we have real gold!! on our sensors (here goes all the lowbudget talk:) but we let the sensors for another post..
