Step 1: Plug in wires to Relay module

A relay acts as a switch– either connecting ('on') or not connecting ('off') the two wires fed into the channel.

Use a pen or a nail to press down on the top of the relay, and feed in the red (power) wire.

The ground wire doesn't go into the relay; it just goes straight to the power adapter.

Step 2: Plug modules in to Tessel

Relay gets plugged into Port A; Ambient gets plugged into Port B.

Step 3: Plug in Tessel to USB

Plug in the Tessel to your computer. This provides power and lets you push code.

Step 4: Plug in power to the lights

Not the lights. I've been playing around with electrodes + Tessel lately: https://github.com/Frijol/Tessel-GPIO-EMG
