Vizy has an optional light that can be used to offer subject lighting. It can be controlled from software running on Vizy.

1. Attach the mount to the light with the thumb screw.
   
2. Attach mount to lighting mount on Vizy by sliding into the slot and tightening the thumb screw.
   
3. Attach power cable to terminal connector as shown. Note the location of the polarizing “nubs” shown by the arrow. Pin 1 gets the black wire, and pin 2 gets the red wire. Note: when using the terminal connector, first loosen the connector's fasteners by turning them counter-clockwise to open the internal clamps. Then insert the wires and tighten by turning the fasteners clockwise. Tug on the wires to make sure they are secure. Your Vizy screwdriver is perfect for this job.
   
4. Plug in power connector to light.
   
5. Plug terminal into Vizy.
   
6. Switch on. (This will not yet turn on the light yet – see below.)
   

The light is software-controlled and normally the pins on Vizy's I/O connector don't supply power until you tell them to do so. The easiest way to enable power (currently) is through Python code, or by bringing up a Python interpreter.

To quickly test things out, turn on your Vizy and point your browser to it. (Please refer to the getting started guide if you need help with connecting to your Vizy, etc.) Bring up a Python interpreter by clicking on the ☰ icon in the upper right corner and selecting Python.

This will bring up a Python interpreter. Within the interpreter type in the following:

from vizy import VizyPowerBoard
pb = VizyPowerBoard()

Then to turn on:

pb.vcc12(True)

To turn off:

pb.vcc12(False)

Note, this is just for testing. Applications will do this in a more automated way!

While the light is on, you can adjust the brightness and color temperature and it will remember the settings between power cycles. Just turn the knob to adjust the brightness. Press the knob as if it were a button and turn it to begin adjusting the color temperature.
