We now need to select the device to which to upload code. Clcik the

devices icon in the IDE.

If you have just one Photon claimed, it will be the only device to choose

from. If you have more than one Photon, you will need to select the star

next to the device you want to program.

With the example open, click the verify button to make sure the code

compiles correctly.

Once verified, click the upload button to program the Photon.

You should see the Photon’s RGB LED blink magenta for a few seconds

indicating it’s being programmed.

Firmware Updates: If this is the first time you've uploaded code to

this Photon or if you haven't used this Photon in awhile, it may go

through an automatic firmware update. These typically take less than

a minute and are indicated by the RGB LED blinking magenta very

sporadically. Once complete, your firmware should be uploaded. If

your device has any issues during or after the update, hit reset on the

Photon, and try again.

Once your code is uploaded, the RGB LED should go back to breathing

cyan to indicate it’s connected and running.

Now, open your favorite serial terminal program. Connect to the Photon at

9600 baud, and open a terminal.
