||
|
|
Turns on an LED on for one second, then off for one second, repeatedly.

|
|
To upload to your or Trinket:
|
||
|
|
1) Select the proper board from the Tools->Board Menu (Arduino Gemma if
|
||
|
|
teal, Adafruit Gemma if black)
|
||
|
|
2) Select the uploader from the Tools->Programmer ("Arduino Gemma" if teal,
|
||
|
|
"USBtinyISP" if black Gemma)
|
||
|
|
3) Plug in the Gemma into USB, make sure you see the green LED lit
|
||
|
|
4) For windows, make sure you install the right Gemma drivers
|
||
|
|
5) Press the button on the Gemma/Trinket - verify you see
|
||
|
