Pololu 3pi+ Robot Library 🤖

Welcome to the Pololu 3pi+ Robot Library repository! This repository contains everything you need to get started with programming and using the Pololu 3pi+ robot with Arduino IDE. The Pololu 3pi+ is a versatile programmable robot designed for educational and hobbyist purposes, featuring various sensors, motors, and a programmable microcontroller.

Getting Started ⚡

To get started with using the Pololu 3pi+ Robot Library, follow these steps:

1. Driver Setup:

• Download the A-Star Windows Drivers [https://www.pololu.com/file/0J1240/a-star�windows-1.3.0.0.zip] (7k zip) and extract the ZIP file to a temporary folder on your computer

2. Arduino IDE Setup:

• In the Preferences dialog, find the “Additional Boards Manager URLs” text box (highlighted in the picture below). Copy and paste the following URL into this box:
• https://files.pololu.com/arduino/package_pololu_index.json
• In the Tools > Board menu, select “Boards Manager…” (at the top of the menu).
• In the Boards Manager dialog, search for “Pololu A-Star Boards”.
• Select the “Pololu A-Star Boards” entry in the list, and click the “Install” button
• Use blink.ino to check if setup is done correctly
