Hello everyone,

I am a young French student in mechanical engineering, and I decided, during my spare-time, to start assembling the SmartWatch. So I received last week the SmartWatch kit from TinyCircuit.

   I use the software Arduino 1.6.13 on MacOS Sierra, I have downloaded the library Tinyscreen +, different Driver to read the port and I followed all the instructions of the website but when I compile code BasicExample, the software IDE returns the error "No device found on cu.usbserial-DO00BMOM". For information, the LEDs on the electronic board blink when I plug it into the USB port but the screen never turned on (produce light).
   I also tried to run the card on a friend's PC (Windows 10) and the IDE displays the same error "no device found on COM3". We tried all the ports on the computer without success. I also changed the cuddle to eliminate this potential mistake.

Does anyone can help me to begin my TinyDuino experience please?

(Ps: I'm really sorry for my basic level in english. Please ask me more details if you need it.)

Thank's
