servo on arduino uno works , but not with nano

[Corvl]

Hello all,

I have an arduino uno with a servo succesfully installed, but the arduino was just for testing purposes.

Ijust recieved my 2 nano's ( http://www.ebay.de/itm/291244948748?_trksid=p2060778.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT )

installed everything and uploaded the sketch , just to be sure I deleted the 2 devices I allready had ( the arduino node and the arduino win covering) . I press start to include , nothing happends.

Tried the second nano, exactly the same , tried to upload the sketch with "#define CHILD_ID 11 // Id of the sensor child " instead of 10 ( maybe an issue since the uno used 10 ).

But still the same .

Deleted the whole my sensnor plugin and tried all again...... no luck with the nano's.

My last resort was to use again the uno , I press start to include , and yes , almost immediately the 2 devices were found.

What can be wrong??!

Attached 2 pictures of the connection , but I don't think I did that part wrong.

Hopefully someone can help,

Thanks,
Cor

@Corvl be careful i lost 4 nanos with servo
dont give power from nano to servo

• try clear eeprom before uploding a sketch

Thanks , I will use a seperate power source for the servo , as soon as I can include the device on my vera.

What do you mean , clear eprom ? , I used my UNO get a bootloader in the nano : http://www.instructables.com/id/How-To-Burn-a-Bootloader-to-Clone-Arduino-Nano-30/step3/Simple-few-steps/

That's not good enough?

Thanks for your help ,

On MCV forum someone came with the solution. it seems that this nano I have does not have enough output on the 3.3v pin for the shield with external antenna I wanted to use.

It is working with the shield without external antenna. Checking now if it is possible to have the full output with external antenna on 5v with a 3.3v regulator in between.

Thanks,
Cor
