 Bigger Bigger  Smaller Smaller  Reset Reset

UNO board, windows 7 ultimate 64 bit

i loaded all the drivers as per instructions on web site.  opened the blink file and uploaded it.  it works fine.  Then i tried to load the button file and got this message: avrdude: stk500_getsync(): not in sync: resp=0x00

I have since rebooted, changed com ports, usb ports, tried to update drivers.  reset the board and upload.

and just so you know i'm new to every aspect of this... to include posting on a forum!

When you connect the Arduino to the computer does the operating system make the device insertion sound?

If anything other than the USB cable is connected to the Arduino disconnect it.


Edit: Typographical mistake corrected.

That's odd.

You connected just two jumpers?  The first connects TX to RX?  The second connects RESET to GND?

Does the USB cable work with other devices?

i just tried again with a different usb cable and didn't get the chime.  I pulled out the jumpers and plugged it in and got a chime.  then i reinstalled the jumpers and got the chime.  the plugged in chime sounds different than normal.  lower, possibly a sort of not good connection sound.  ran the serial monitor no echo

Try this...

• Disconnect the Arduino from the computer

• Remove the jumpers

• Open Device Manager. 
→ Are COM1, COM3, and COM4 listed under Ports? 
→ Are any Unknown devices present?

• Connect the Arduino. 
→ Did the computer chime?
→ Are COM1, COM3, and COM4 listed under Ports? 
→ Are any Unknown devices present?
