tessel-toggle-client
A ReactJS client to call out to a Tessel 2. This app allows the user to toggle the Tessel 2's onboard red, amber, green, and blue led lights from a browser. Also, just in case your Tessel isn't within range of your eyeballs, the app supports a USB camera connected to the Tessel 2 so you can confirm that the lights do indeed toggle. Or point the camera somewhere else and get video of your Tessel 2's surroundings.
The repo for the Tessel 2 server is here.
