# Test the PCC

## Physical Setup:

On your PCC, we'll need to make use of a USB power jumper to power the servos from our laptop. \ <br>

![Installed USB power jumper](https://734487356-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-MObZEFR6zG-gnkxXVBb%2F-MX_Wiup5it5mRxbnvGF%2F-MX_X10S0TGqBE9d78Ca%2FDSC02217.jpg?alt=media\&token=dd1fc909-de0a-41c5-989e-46598189973f)

{% hint style="danger" %}
MAKE SURE to **ONLY** use the jumper when testing with your laptop. **NEVER** use the USB power jumper when the PCC is connected to the Jetson. This is because the servos may draw enough current in certain scenarios that would cause the current protection to trip on the power supply and power off the Jetson regardless of what it's doing.

Plug your servos and LED strip into the designated connections on the PCC:

* The LED strip plugs into the prop-maker featherwing&#x20;
* The servos plug into channels 0-3, with the yellow signal wire of the servo facing the Adafruit logo on the PCB.

### Back at the Computer:

Open VS Code

* Open PCC -> Python folder
* On the bottom left, select our VRC env

* Connect the PCC to your computer.&#x20;
* Open the gui\_test.py file
* Click the play button

* Select the COM Port that corresponds to your PCC (I have tried on two machines, it should enumerate to COM 6)

{% hint style="success" %}
Click around and try the different buttons, your PCC should light up the LED and move some servos!
