Hi there,
I just purchased my first Arduino. I tried to upload one of the examples first, just to test and make sure I could upload, and that's when problems began. I couldn't upload anything.
I am using a Mac Pro with OS 10.5.8. I understand I need no drivers for the UNO, but even so, I ran the driver file that comes with the Arduino software. I selected the proper arduino in tools and I selected the TTY port. There are many ports but only one is USB, it's obvious and I am only unsure about the two "versions" shown, tty and cu.
When I try to upload anything (hitting the upload button) I see an error message saying the following:
Binary sketch size: 970 bytes (of a 32256 byte maximum)
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_recv(): programmer is not responding
I only get this message once. After the first time it just freezes and most times I can't even close the software and I've been rebooting.
I found that Mac locates the Arduino within networks. I don't know if I should configure the "modem" in any way. Most info online says I don't have to do this.
My Arduino came with a blinker program already loaded, so it keeps blinking when I connect it, but I have never seen the TX or RX LEDs to show any signs of life. I'm getting nervous, desperate and hungry. I want to start playing with my new cool toy.
What may I be doing wrong? Any ideas will be greatly appreciated.
Thanks a lot.
Bernardo
