Lower digit COM devices are usually reserved for hardware so that is right.
If the yellow light is flashing it is trying to respond, so try a different USB cable.
Try re-downloading the driver, if it still does not work use the reset
button on the UNO, only as a last resort.

Have you made sure your selecting the right Board in the list. I made the mistake when transferring to a new PC. Simply FORGOT to select my Mega 2560

Hope this helps.

I got this recently. The serial COM port disappeared completely also. Deleting and then reinstalling the FTDI driver seems to have fixed it for me.

[post-edit] another instance was my USB cable was flaking out due to a flakey connection on the data pins. I threw it out and replaced it with a different cable. All is good

This error is usually caused by the chip is missing the bootloader.

hi guys, we're new here.
we're trying to connect our Arduino Nano (ATmega 328) with our Pololu Mini Maestro 24 channels through the rx/tx pins.
we've found some people over the internet that succeeded to do this kind of connection but we can't manage to make it work
we've connected the arduino USB to our computer
both arduino and maestro GND pins to the GND of our supplier
maestro VSRV to 5v from the supplier
maestro VSRV to the maestro VIN pin
arduino tx to maestro rx, arduino rx to maestro tx
(attached is a picture of the wiring)

we've used the following codes with rx pin - 0 and tx pin - 1(on arduino Nano) -
http://www.darrenfeetham.com/18ssc.html(last one)
http://www.quantumphysguy.com/2013/07/0 ... o-maestro/

and we get this error everytime - avrdude: stk500_getsync(): not in sync: resp=0x00
we've checked the COM port and that the BOARD setting in the compiler is correct

we've also tried to use the example code from the Arduino site regarding the SoftwareSerial library -
http://arduino.cc/en/Reference/SoftwareSerial
and it didn't work :(
afterwards we've disconnected to Maestro and tried again, and Voila! working.
so, does anybody know what might be the problem?
we're desperate.

thanks!

@omryofec First off, welcome. Second, you should start your own thread when you have a new problem not link to a two year old post. Third, you should post your actual code between

Code: Select all

 tags or attach it to your post and Fourth, that error usually means you have the wrong board selected in the IDE.

SOLVED

Pro Trinket (Windows 7, USB) Steps:
1. Tools: Board: Pro Trinket 5V or 3V...
2. Tools: Serial Port: This does NOT matter. You do not need select a "Port". Com(#) Look under your device manager. This may say "Communications Port(COM1). The Pro Trinket does not show up like other Arduinos. It shows up under LibUSB-Win32 Devices (USBtiny)... (ie. COM1, COM3, COM9...)
3. Tools: Programmer: !!! USBtinyISP !!!

The Green LED should be on.
The RED LED should pulse during blinking.
If it is not, TRY:
Press the reset button on the trinket (RED LED pulses when blinking). IF NOT THEN
Unplug the USB from the Computer, then plug it back in (RED LED pulses when blinking).
The pulse blink lasts about 10 seconds.

4. Upload Sketch.

If it still does not work. Close your Arduino IDE. Unplug the Pro Trinket. Wait... Plug in the Pro Trinket. Wait... Start the Arduino IDE. Check: Board, Serial Port, and Programmer under Tools...
https://learn.adafruit.com/downloads/pd ... rinket.pdf

NEW: I updated Arduino IDE to 1.6.0 and poof! all my boards are gone. Oh well. My fault for just updating it without reading more... If you can't find your Pro Trinket board after updating - Follow the instructions here:
viewtopic.php?f=52&t=67018#p340144

NOTE: The adding of the "/avr/" folder in the /hardware/Pro Trinket/ folder. And the change and addition of .txt files.
Good Luck.
Chuck
