Basic Assembly and Setup

Hi, I hope someone has some help for me.

My thumbs are sore from the springs but I'm ready to calibrate and put my legs on!

Here is my current situation: I was able to use my Win 10 computer to connect to the Bittle via USB. I tried loading WriteInstinct first ... and it kind of worked. It uploaded but maybe only partway. Here's the printout (115200/No line ending)

Then it just sits there. It won't take any inputs. Sometimes it will run this sequence this over and over on its own.

The other problem is that now, I cannot load any other project -- I get the avrdude errors other people have seen:

        System wide configuration file is "C:\Program Files (x86)\Arduino\hardware\tools\avr/etc/avrdude.conf"

avrdude done.  Thank you.

An error occurred while uploading the sketch

At one point, I was able to compile and upload the testInfraredRemote sketch successfully (including the head turning!), but then I tried WriteInstinct again and now I can't upload anything else. I've tried OpenCat, testBuzzer, testSerialComm and nothing new happens except the battery gets lower and every time I open the Serial terminal, it re-runs the original output.

Are the LEDs diagnostic of anything? From 0-6, they are:

0 1 2 3 4 5 6

grn grn grn red red off off

I've tried (multiple times and combinations):

• Restarting Bittle

• Unplugging/plugging battery

• Unplugging/plugging USB cable

• Changing USB ports

• Reinstalling Arduino

• Reinstalling the libraries

• Reinstalling the USB driver

• Rebooting computer

• Reading this forum

• Reading other forums about Arduino

• Going to bed for the night

  • Charging the battery fully as I sleep

Thanks for any thoughts!
