Simple Arduino projects for beginners.

Friends! I continue to experiment, despite the dire health situation around the world. This is one of the simple projects of moving the robot along a curved trajectory with the ability to avoid obstacles. I used to use an ultrasonic rangefinder, but now I decided to try an infrared rangefinder. Stability of movement work on the infrared rangefinder has become better. In the future, I plan to improve the program code so that the robot's movement becomes even smoother. As in the case of an ultrasonic rangefin
