Ultrasonic sensor showing 0. RS to Arduino pin 11. This means that Nov 24, 2024 · I am trying to make a radar with to ultrasonic sensors that are at a 30ish degree angle away from each other. Any idea of what's going wrong? [Solved: fucked up the wiring] Apr 15, 2024 · I'm building an ultrasonic sensor for my rain water tanks. I decided to use an average of 10 readings instead of a single reading, since there's some noise. The issue im facing is that one of the sensors always returns 0 when i call the pulsein command. I do not understand what can affect its performance as it works fine in my other sketch. If on detects an object, they will turn to try ad face the object. But I'm having a strange problem when I read the sensor in a loop, which is that every other reading is 0. Before I added the loop I was reading Aug 21, 2016 · I made my code a lot more concise since the posted code draft, but the ultrasonic sensor still gives me 0s. VEE to Arduino GND. Oct 1, 2019 · HC-SRO4 always returns zero no matter what I do? Wondering if it's the sensor or the code? can anyone help? I've used the code here. Feb 13, 2017 · ultrasonic sensor always showing 0 value Projects General Guidance raj412 February 13, 2017, 7:20am Aug 12, 2021 · Sensors 9 714 May 6, 2021 HC-sr04 not working straight out of the box Sensors 20 164 May 1, 2025 Ultrasonic sensor HC-SR04 General Guidance 7 1252 May 5, 2021 HC-SR04 always returns zero Sensors 23 69803 May 6, 2021 Issue using HC-SR04 with Uno Sensors 4 2881 May 6, 2021 When i run a test code in Newping library for ultrasonic sensor SR04 then in works properly but when i run the actual code for obstacle avoiding robot then it shows 0 cm everytime. Jun 30, 2015 · I am doing a basic project in Arduino UNO connecting an Ultra Sonic sensor (HC-SR04) which should print in the serial monitor the distance of the closest object but it always print 0. . Jun 29, 2021 · So for the school project i had to make the ultrasonic sensor measure distance which he will write on serial monitor and lcd ( i did those two and they work perfectly) but also add wireless module to it that will send it… In this guide, we will explore potential reasons why your ultrasonic sensor isn't functioning as expected and provide a simple, effective solution to get your project back on track. Not sure if it's because I'm reading too quickly, or if I'm doing something obviously wrong. I am certain that both sensors are not broken and that the wiring is fine. Jan 22, 2020 · It just keeps spitting out "Ping: 0cm". Trig to Arduino pin 13. So it would seem that if there is nothing in front of your sensor closer than 500cm, this library returns 0cm. R/W to Arduino pin 10. I am sure that the issue is not interference Dec 10, 2018 · I have been working with ultrasonic sensors for a while but never encountered anything like this but, now a days am facing one problem ,my ultrasonic sensor is not giving me correct readings just showing '0' as distance even when am trying a simple code. Jan 21, 2014 · I found about 2 hours later, after reading a dozen forums, that the main issue that was causing my ultrasonic sensor to return zero while using the NewPing library is that pin 1 and other pins cause the ultrasonic sensor to not function properly. E to Arduino pin 9. GND to Arduino GND. VCC to Arduino 5V. Probably not the best design, but at least it is disclosed. Here's a pic of my set up. VSS to Arduino GND.
