Obsticle Avoiding Arduino Rover

Converted Snap Rover to Arduino Obstacle Avoiding Automatic Roaming Rover. Attached is the working Arduino sketch file for this project. To get started, download the library for the motor shield at: https://learn.adafruit.com/adafruit-motor-shield/library-install. Here are the items you'll need: 1. Snap Rover - https://www.ebay.com/i/122959754766?rt=nc 2. Arduino Uno Board 3. Arduino Motor Shield 4. Parallax Standard Servo 5. HC-SR04 Ultrasonic Sonar 6. Two adjustable voltage regulators (one set to 5V to power the Arduino and another set to 9v to power the motor shield) You can find these regulators at: https://www.ebay.com/itm/10pcs-Mini360-3A-DC-Voltage-Step-Down-Power-Converter-Buck-Module-3-3V-5V-9V-12V/132416658988?epid=1402279667&hash=item1ed4a5de2c:g:mLMAAOSwRlhapFRp. When using the motor shield, connect motor output 1 and 4 to it. The sonar should be connected to 5VDC and Ground, with Trig going to A4 and Echo going to A5 on the Arduino pins. The servo should be connected to (servo 2) on the shield. The battery mount is designed for an XT60 connector and a toggle switch 12x20mm socket, similar to those found on computer power supply boxes. This setup runs off a 3S LiPo battery. Note that my motor shield had a problem with only having 3.5V on the 5V pins, so I connected the servo and sonar directly to the output of the 5V voltage regulator, which powers the Arduino. Have fun building this project! If you find it interesting, be sure to like it.
