I am trying to program my Arduino Uno for the first time using the “Blink” sketch in the examples folder, but when I try to upload the sketch, I get the following error: avrdude: stk500_recv(): programmer is not responding.
This happens when the upload bar gets to about 90% complete. I am also able to see the RX LED on the board light up, but not the TX. To my knowledge I have selected the proper board and serial port from the “Tools” menu. I am running Mac OS X 10.5.8.
An image of the error is attached as a PNG, but let me know if more information is needed. I haven’t been able to find anything that resolved the issue in the forum or FAQs. All help is appreciated…Thanks.
