The internal analog to digital converter is used is calibrated to get almost accurate distance measurement. The measured distance is also displayed on an LCD screen.N. Anju LathaB. Rama MurthyK. Bharat KumarIJARIIT
Arduino - Ultrasonic Sensor Arduino - 超声波传感器的实现 Arduino’s pins can generate a 10-microsecond pulse and measure the pulse duration. Therefore, we can get the distance from the ultrasonic sensor by using two Arduino’s pins: Arduino的引脚可以产生10微秒的脉冲并测量脉冲持续时间。因此,我们...
