I did this project as an "Introduction to Arduino".
What it Does
The rover drives forward until something is detected by the ultrasonic sensor. Then the rover turns to the left and continues until it again detects an obstruction.
How it's Made
Most of the hardware pieces came in a kit. I put the kit together and then programmed it in the Arduino IDE
Where it's Going
This rover can be improved greatly. If I wanted to continue working on it, I would get a better ultrasonic sensor and include more features like the option for remote controlling it.
