Arduino Uno HC-SR04 + Servo

This is my one of my first Arduino project. It is an HC-SR04 connected with a servo + laser + led. It can read the distance and notice if the object is closer, in the same place or further away. It projects different laser-patterns and it writes various text in the serial function depending on this. PS i&sorry for some of the wrong values, it is because it reads the table in some angles.
