![]() 4 sensors ( ultrasonic, sound, touch, and light ), 7 connection cables. The reason is that 10 inches are equal to 25 centimeters which is 2. The Lego MINDSTORM EV3 brick Sound blocks play tone mode uses a frequency. This leads to giving incorrect instructions to the sensor which results in a failure of the program. Some information about metric unitsĪ possible mistake is to forget to change inches to centimeters. In the example shown on the picture the value is set to 50 cm, but the sensor can detect distance between 3,01 cm and 255 cm. Locally generated ultrasonic noise at the sensor operating frequency can. Ultrasonic sensors measure the distance to or presence of a target object. So In theory its minimum range is 0 cm and its maximum range is 254 cm. ![]() "=") as usually the robot passes the respective value too fast and fails to detect it and react as programmed. The value of 255 has a special meaning, it indicates there is no object within measuring range. Choosing the measured distance threshold-value the robot should wait forįrom the first dropdown menu we choose whether the robot to react at a distance:Īvoid the "equal to" option ( i.e. By default the ultrasonic sensor connects at port №4. The function of the Ultrasonic sensor is to measure the distance to objects. ![]()
