# Team 65266 Lego Dynamics - PYNAMICS - Pybricks Utilities # Team 65266 Lego Dynamics - Pybricks Utils
A collection of Pybricks utilities to assist in your FLL robot programming with Python. Created by FLL team 65266, Lego Dynamics. A collection of Pybricks utilities to assist in your FLL robot programming with Python. Created by FLL team 65266, Lego Dynamics.

How to use this:
- Download the repository by clicking on the "Code" tab, clicking the "< > Code" button, then downloading as a ZIP. Additionally, you can also use ```git clone https://codes.fll-65266.org/Arcmyx/pybricks-utils.git```. Unzip the archive and open code.pybricks.com. Then choose which folder you'd like to use, and open each file in pybricks by using the import button. For example, to use the diagnostics tool, simply open each program in the ```diagnostics``` folder into Pybricks. Then, follow the instructions for each utility.
Included utilities: Included utilities:
- Diagnostics - a program that prints out useful information like battery life, etc.
- Diagnostics - a program that allows you to diagnose issues and test parts of your robot, such as battery, motor, and color sensor. Open each program in the ```diagnostics``` folder in Pybricks, connect your robot, switch to the ```FullDiagnostics.py``` file and press run. - Color Sensor Tests - a program that identifies what color the sensor is detecting. If you'd like, you can use our color ranges in your own programs.
- Color Sensor Tests (UPCOMING) - a program that identifies what color the sensor is detecting. If you'd like, you can use our color ranges in your own programs.
