this research uses experimental methods to design a tool to measure the distance between the transmitter and receiver with an ultrasonic sensor initially ultrasonic waves were ultrasonic signal with a frequency of less than 40 khz will be transmitted for 200us. wave it will travel through the air at a speed of 343 m/sec (or 1 cm every 29.034us), then will be controlled by atmega328.
