How To Measure Distance Between Two Ultrasonic Sensors

Ultrasonic sensor (HC-SR04) is commonly used to find the distance of an object from one particular point. It has been fairly easy to do this with the Arduino and the code is also pretty simple. But in this article we are going to try something different with these popular HC-SR04 sensors. We will try calculating the distance between two Ultrasonic sensors that is, we will make one sensor to act as transmitt ...

Smart Blind Stick using Arduino

Ever heard of Hugh Herr? He is a famous American rock climber who has shattered the limitations of his disabilities; he is a strong believer that technology could help disabled persons to live a normal life. In one of his TED talk Herr said “Humans are not disabled. A person can never be broken. Our built environment, our technologies, is broken and disabled. We the people need not accept our limitations, b ...

Ultrasonic range finder using arduino

Ultrasonic range finder using 8051 mictrocontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment display. This range finder can measure up to 200 cm and has an accuracy of 1cm. There is an option for displaying the d ...

Arduino Based Distance Measurement using Ultrasonic Sensor

Ultrasonic sensors are great tools to measure distance without actual contact and used at several places like water level measurement, distance measurement etc. This is an efficient way to measure small distances precisely. In this project we have used an Ultrasonic Sensor to determine the distance of an obstacle from the sensor. Basic principal of ultrasonic distance measurement is based on ECHO. When soun ...

Ultrasonic Dimmer

I have been working on this project for a while and whilst it is still under development I decided to write a short guide after several requests to do so. The dimmer uses an interrupt driven XL-Maxsonar EZ1 ultrasound range finder to measure the distance between the sensor and your hand. By moving your hand up and down over the sensor you can increase or decrease the amount of light emitted by the connected ...

Arduino Ultrasonic Parking Spotter

For my first instructable, I'd like to present The Parking Spotter. This is not a new concept, I know. However, this build was done specifically to suit my needs/wants/materials already in my possession. Typically, a project begins with an idea, parts are then gathered, and the building commences. In my case I looked around at the parts and material that I had on-hand, browsed Instructables (a daily occurre ...

Arduino Project # 1 – Make an Ultrasonic Distance Calculator

Arduino Project – The distance calculator I have been playing with Arduino (micro-controller) for about 2 years now and I am becoming more and more passionate about circuits. For those who are not aware of Arduino, check out my article “Arduino – A Guide for Beginners“. Recently, I was testing some new components that I ordered, which included an ultrasonic sensor and an LCD. I found an article online that ...

Ultrasonic Range detector using Arduino and the SR04 Ultrasonic sensor

his is a preliminary instructable that will take you through the steps I took to get the SR04 ULTRASONIC SENSOR  connected  and working to the Arduino. It will then be incorporated to my mini environment monitor.  Eventually, if it all fits, it will end up in a Startrek  toy tricorder casing I found in my junk box.. Step 1: Connecting the SR04 Ultrasonic Sensor to the Arduino Step 2: Parts List 1           ...

Arduino Ping Ultrasonic Range Finder Code

The Ping))) is an ultrasonic range finder from Parallax. It detects the distance of the closest object in front of the sensor (from 2 cm up to 3m). It works by sending out a burst of ultrasound and listening for the echo when it bounces off of an object. The Arduino board sends a short pulse to trigger the detection, then listens for a pulse on the same pin using the pulseIn() function. The duration of this ...
