The code includes two Arduino libraries: one for the servo and another for the ultrasonic sensors. The main code is a simple 14-line piece with a simple if-else statement you can readily modify.

The readability of your code can make the difference between your project being a joy to work on, or an absolute headache. This goes double when collaborating with others. Having easily parsed code… ...

There are also no libraries used in the program, just straightforward if-else statements and function declarations, so this is one of the best Arduino projects for beginner coders to try.

Open the Arduino software and paste the Arduino code (the text in the box near the bottom of the post) into a new sketch. Click Sketch > Verify / Compile to make sure the code is properly in there.
