Parking Sensor based on Arduino

Sustav za parkiranje je postao standardna oprema u većini vozila. Najosnovniji i najjednostavniji sustav za parkiranje zvučno i vizualno obavještava vozača u kabini o udaljenosti vozila od prepreke. Za upravljanje sustava realiziranog u ovom radu korišten je Arduino mikrokontroler. Korišten je ultrazvučni senzor koji detektira udaljenost. U ovom sustavu korištena su tri senzora za udaljenost. Za vizualnu signalizaciju korišten je OLED ekran na kojem se ispisuje udaljenost koju je prethodno izračunao Arduino mikrokontroler. Za zvučnu signalizaciju korišten je buzzer koji daje kratkotrajne zvučne signale. Između kratkotrajnih zvučnih signala postoji vremenski razmak koji ovisi o najkraćoj udaljenosti vozila od prepreke. Što je prepreka bliže vozilu to je vremenski razmak kraći između zvučnih signala.Parking assist system has become part of the standard equipment in most vehicles. The most basic and simplest parking assist system emits acoustic and visual signals to inform the driver inside the car cabin about the distance between the vehicle and the obstacle. The Arduino microcontroller, which is described in this final paper, was used to manage the system. An ultrasound sensor was used to measure the distance. Three different distance sensors were used in this particular system. The visual signalization consists of the OLED screen on which the distance, previously measured by Arduino microcontroller, is indicated. The acoustic signalization consists of a buzzer that emits short acoustic signals. The time intervals between the brief acoustic signals depend on the shortest distance between the obstacle and the vehicle: the closer the obstacle is to the vehicle, the shorter is the time interval
