Hi, I'm novice in this language, but i have to do a project wich includes an ultrasonic sensor, HC-SR04 . The project is similar with this one https://www.youtube.com/watch?v=1OOPsGeDk0E , but instead of using PING)) sensor i have to use HC-SR04. Can you guide me with all steps I have to modify in schematic and code ? Thank you very much!
L.E: Also, I can make my project as this one http://www.instructables.com/id/Arduino-Distance-Detector-with-a-Buzzer-and-LEDs/step7/The-Code/ but also i have to connect a LCD 16x2 .
