![]() ![]() Vcc (+5V) : You need to provide +5V at this Ultrasonic Sensor HC-SR04 Pin.This sensor consists of four pins, which are:.The sensor has a transmitter and a receiver on it." "Ultrasonic Sensor HC-SR04 is a simple sensor which emits Ultrasonic Radiations from its transmitter and is used for measuring the distance between sensor itself and any obstacle in front of it.So, today I am gonna interface an Ultrasonic sensor with arduino and will check its output on the Arduino Serial Terminal. ![]() ![]() :) So, the bottom line is never trust simulations, unless you properly test it on hardware. It happened to me a lot of times that my simulations are working perfectly fine but when I design the same circuit in hardware then it says no I am not gonna work. Simulation is a good starting point for projects but they are really far away from real world. Those posts were about Proteus Simulations and weren't about hardware interfacing, so I thought today let's interface it in hardware. Few days ago, I have posted a complete tutorial on How to Use Ultrasonic Sensor Library in Proteus and later I have posted different examples on How to Simulate Ultrasonic Sensor in Proteus. Today, we are gonna have a look on How to Interface Ultrasonic Sensor with Arduino.
