PID-based one-axis ball balancing robot using Arduino. Uses an ultrasonic sensor and servo motor to stabilize a ball at a target distance. Real-time tuning of Kp, Ki, Kd via Serial. Includes stability ...

Ultrasonic sensor measurements are mostly based on the determination of the time of flight (TOF). The development of a digital algorithm for pulse-echo measurement applications, based on the use of a ...

The Arduino code is located in the arduino-code folder. The code still lacks the ability to measure pressure and it is a mess (I merged several online projects). It measures the pressure in mV. As ...
