On the other hand, the Arduino IDE only lets you program Arduino boards with the Arduino programming language, which is based on C++. With that over, let’s make the Arduino blink its internal LED!

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.
