Lab 1: Intro to the Arduino, Servos & US Sensors

In this lab, we built and programmed a robot using a 9V battery, four AA batteries, two servos, three ultrasonic sensors, and an Arduino Nano Every to navigate through a simple maze.

The navigating robot will do the following:

1. Start in position 1, immobile.
2. Once you press the RESET button on the Nano, it will remain motionless for 1 second, then head North towards position 2.
3. Once at position 2, it will turn smoothly in place to its left to face West, then navigate towards position 3.
4. Once at position 3, it will turn smoothly in place to its left to face South, then navigate towards position 4.
5. Once at position 4, it will turn smoothly in place to its right to face North, then navigate towards position 3.
6. Once at position 3, it will turn smoothly in place to its right to face East, then navigate towards position 2.
7. Once at position 2, it will turn smoothly in place to its right to face South, then navigate towards position 1.
8. Once at position 1, it will turn smoothly in place to its left 540 degrees (1 ½ turns) ending facing North where it will remain in place stationary.
