Datasheet http://www.micropik.com/PDF/HCSR04.pdf Notes The HC-SR04 is one of the lowest cost Sonar-based distance sensor options available (as low as $3 US). There seem to be several hardware versions and/or clones that work the same as far the functions of the two pins (trigger ...
HC-SR04 Datasheet Wiring – Connecting HC-SR04 to Arduino UNO The wiring diagram below shows you how to connect the HC-SR04 sensor to the Arduino. HC-SR04 with Arduino wiring diagram The code examples below use digital pin 2 and 3 for the trigger and echo pin respectively, but of course...
To measure the distance, 1, send a high voltage from pin PC5 to trigger, Luke used 5us, but the HC-SR04 datasheet says at least 10us. Confusion 1. 2, we set the timer basic unit as 74 cpu cycles, that is 5us. 3, once the PC5 is set to high for that 5us (or 10us), ...
}longmicrosecondsToInches(longmicroseconds){// According to Parallax's datasheet for the PING))), there are 73.746// microseconds per inch (i.e. sound travels at 1130 feet per second).// This gives the distance travelled by the ping, outbound and return,// so we divide by 2 to get ...
