Where can I find the WiFi config file to copy onto my SD card?

Download the config file at https://www.emotibit.com/files/config.

Open the config file in any text editor and change myWifiNetwork, to the name of your WiFi network and change myPassword the password for your WiFi network. Then save the file onto your microSD card, insert the microSD card into your EmotiBit and hit the reset button on top of the Adafruit Feather. 

If your credentials are correct and your WiFi network is in range, after about 5-10 seconds of boot up your EmotiBit should automatically connect to your WiFi network. The green WiFi LED on the Feather will light up and your EmotiBit will show up in the EmotiBit Oscilloscope device list. If data streaming doesn't immediate begin, check the box next to your EmotiBit to connect.

Pro tip: If you use multiple WiFi networks and want your EmotiBit to automatically connect to whichever one is in range, simply add both networks to the WifiCredentials array in the config file like this:

 {
  "WifiCredentials": [
    {"ssid": "myWifiNetwork1", "password" : "myPassword1"},
    {"ssid": "myWifiNetwork2", "password" : "myPassword2"}
  ]
}
