• Open the USB drive that appears and modify the config.txt file to input your Wi-Fi SSID and password.

• Save the file. (Do not save the file multiple times.) Power cycle the WIAnode to restart it.

Step 2: Connect the Sensor

• Use a 4-pin silicone cable to connect the LED sensor to the I2C port on the WIAnode.

Step 3: Connect TouchDesigner to WIAnode

• Press the WKUP button on the side of the WIAnode to wake up the screen (it will turn off automatically after one minute of inactivity) and check the current device IP address.

• Open the TouchDesigner example file, click on the WIAnode plugin, and enter the IP address shown on the WIAnode screen into the configuration panel. Enter wianode as the client name and dfrobot as the password.

• Once the plugin displays Connected, the connection to the WIAnode is successful.
  

Step 4: Control TouchDesigner with the WIAnode Knob
