Control stepper motor using Ultrasonic sensor - Arduino Forum
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 …
Ultrasonic sensor not working properly. - Arduino Forum
Jan 17, 2017 · Using ArduinoSensors. shadow0000 January 17, 2017, 4:31pm 1. I am using a HC-SR 04 Ultrasonic Sensor and it is not responding as expected. It gives a few readings at first and then does not respond at all. I am using the NewPing Example code. Please tell me is that a problem in the code or the sensor itself.
Ultrasonic Flow Meter - Project Guidance - Arduino Forum
Mar 17, 2017 · Ultrasonic Flow Meter. Using ArduinoProject Guidance. Xhale March 17, 2017, 2:30am 1. Hi! I was working on a flow meter with Arduino that used a turbine, but I was thinking that it would be cool to use an ultrasonic sensor instead. My current plan is to use something like the Arduino Uno and two SR04 ultrasonic sensors.
