Jan 15, 2025 · i have been trying to work with Waterproof ultrasonic sensor AJ-SR04m but i am not getting any genuine outputs from it .I have tried its mode 1 which requires open ckt. i.e no short ckt. at R19 . I am currently using Arduino UNO as the microcontroller . IF anyone has previously worked with it successfully .Kindly help. The code I am using :- #define TRIG_PIN 9 …

Apr 28, 2023 · Hello, would like to ask for help, why is my value in dashboard only 0? but when I check it in my serial monitor, my code works well. I am using an ultrasonic sensor and ESP8266. It is already connected in IOT Arduino and WIFI but nothing happens in my dashboard. thank you. below is my code.

Aug 10, 2018 · Hi..i'm new to Arduino. I need a help is Programming Arduino for my project. I need to control 2 Unipolar Stepper motors(28BYJ-48) using ultrasonic sensor HC-SR04. Two stepper motors should run continuously and when the ultrasonic sensor gives a reading of 10Cm from the obstruction, both stepper motors should stop for the moment. Then one stepper motor-1 …

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. But I'm having a strange problem when I read the sensor in a loop, which is that every other reading is 0. Not sure if it's because I'm reading too quickly, or if I'm doing something obviously wrong. Before I …

May 15, 2012 · NewPing Library Project Homepage Background: When I first received an ultrasonic sensor I was not happy with how poorly it performed. I soon realized the problem wasn't the sensor, it was the available ping and ultrasonic libraries causing the problem. The NewPing library totally fixes these problems, adds many new features, and breathes new life into these …

Apr 12, 2014 · Hi guys, I'm new to this and still there's still so much that I can learn. What I'm trying to do is I'm trying to control a 5v DC motor with an ultrasonic sensor. Basically what I want is that the distance determines the speed of the motor, whereas an object that's further away speeds up the motor, and when the object is close it'll slow down the motor. So far no luck, …

Dec 29, 2021 · I would greatly apreciate some help in coding. I am using Ultrasonic Sensor (HC-SR04), a stepper motor, and two limit switch in the end of the motor track. my plan is to control the stepper motor using the ultrasonic sensor. if the distance is more than 20 cm, it should moves to the left (DIR HIGH). if the distance is less than 20 cm, it should moves to the right (DIR LOW). …

Oct 9, 2020 · Hello, I'm new here so sorry if this is the wrong place to post this. I'm trying to run a program that uses multiple HC-SR04 ultrasonic sensors for obstacle detection simultaneously, so that whenever a sensor detects an object less than 20cm away, a corresponding DC vibrating motor will turn on. However, I read online that the pulseIn() function that's used in the standard …

Mar 31, 2022 · Hello 🙂 Edited first post: note: all the recent developments are in my last answer in this thread. As new user I am limited to 15 posts that I have reached quickly in this post. So If you want to read the latest version of my code go to my last answer in this thread. My project is a basketball hoop that gets moved (in the y-z plane) horizontally by two dc motors and vertically …

Dec 4, 2018 · I am trying to combine a ultrasonic sensor and an IR Remote to create a distance sensor. I want to use the remote so that the user can input a distance of their choice and the ultrasonic sensor will measure and light a red LED if it is out of range and a green LED if it is in range. I would also like to program a button that will then restart the program and ask for a …
