Hi hope you can help....
Just purchased a new uno.
First time user.
Loaded upto date software onto a mac book pro running 10.5.8
followed all the points re set up
Copied and verified the code for the blinking led
keep getting fault code avrdude: stk500_recv(): programmer is not responding
Cant find any leads on the forum and sites to help
Tried on another mac running 10.5.8 and no probs
Also keep getting the usb device unplugged window/warning when disconnecting on my pro not the other!
Hope you can help
