2nd Ardunio bought doesn't work!!! Awwww!!!! Please HELP

So I just bought my 2nd Arduino board from Ebay and have been trying everything to get this thing working, 1. Downloaded newest version of Arduino 1.6.6 on my iMac running OS X 10.10.2 2. Connected with USB and 2 led lights come on 3. Checked and made sure correct board was selected 4. UNDER TOOLS>PORT> MY ONLY OPTIONS R .........- /dev/cu.Bluetooth-Incoming-Port /dev/cu.Bluetooth-Modem /dev/cu.Lukesiphone-WirelessiAP 5. when trying to upload Blink Example I get Arduino: 1.6.6 (Mac OS X), Board: "Arduino/Genuino Uno"

avrdude: stk500_recv(): programmer is not responding

Any help would be greatly appreciated! Do I need to burn a boot loader or can I even do that without a Serial port, and if so then which one do I install, Please HELP!!!



Check your device driver, if that looks good try the loopback test, if that is good then bootloader is likely. You need a Programmar connected to the ICSP pins to load that. Still have a working Arduino? Use that as a programmer: http://www.gammon.com.au/bootloader or http://www.gammon.com.au/breadboard

It looks to me like the drivers aren't installed correctly. Note how nothing that could be an Arduino is listed in the list of ports - he's got bluetooth, and some iPhone thing, but nothing that looks like a generic serial adapter or an Arduino. Hence - driver problems (or a dead arduino board, ofc)

Crossroads - he's not even getting far enough for it to be a bootloader problem. Missing firmware on the 16u2 would of course explain it, but I don't think I've heard of that actually happening (usually the clone vendors who would "forget" to bootload chips also use the cheapest serial chip they can get)

is there anything that I am able to do about the drivers? (if it is the case of them not having the drivers installed correctly), I am going to go try them on another computer here in a bit and see if the fault could possibly be in my computer.

Thanks for the HELP

Ebay is a conduit for low-cost counterfeit products. There may be inferior parts or cold solder joints or shortcuts that lead to unexpected problems. A reliable vendor is your best recourse.

Well I took your advise Surfer Dude and ordered one straight from this site, so hopefully I'll have better luck with it



Can you provide a link to the board purchased, or perhaps post a photograph. Some uno clones have the 16u2 for the usb/serial interface and most now have a ch340. You may not have the driver in the later case.


Find the driver for ch340
