Automatic Water Dispenser using Arduino Approximately 71% of the Earth’s surface is water, yet only a meager 2.5% of it is potable. Due to increased population, pollution, and climate change, it is anticipated that we will face year-round water scarcity as early as 2025. On one side, there are already small disagreements between countries and […]

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

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

Have you ever wanted an ultrasonic tape measure, like this Stanley? (See picture). Well, I have but then I am a Lazy Old Geek. I don’t really need one but I thought I’d try to make one. And naturally, I thought of an Arduino. August 2012 update: I just found out the software used in

Time for a follow-up to the Single Button Combination Lock by creating another oddball type of switch/lock. To activate this switch we make use of a Parallax Ping))) Ultrasonic sensor, an Arduino-style board and some other hardware – to make a device that receives a four-number code which is made up of the distance between a hand

Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking the MOD_CH101 ultrasonic time-of-flight (ToF) sensor module and DK-CH101 SmartSonic™ platform from InvenSense, a TDK Group company. The ToF solutions offer fast and accurate range measurement with ultra-low power consumption, and are capable of detecting objects of any

Hello, in this project i want to show and explain you a range sensor with ultrasonic and a 20×04 lcd screen. I wrote the code for this project myself and added lots of comments, so that everybody can understand it and use it for other projects (maybe a light range sensor?!). It is easy to

This project demonstrates the functioning of an “Ultrasonic Mono-pulse Tracker” built using two Grove ultrasonic sensors. Two sensors facing forward at a small angle from each other are placed on a servo pedestal capable of rotating +/- 60 degrees based on commands from an Arduino UNO board. The “Amplitude Comparison Mono Pulse” principle demonstrated here is

This simple Arduino project can be placed in the doorway of a shop or other venue to count the number of people inside. Limiting the number of people inside a space can help to maintain social distancing. A demonstration of this project can be found here. There is no soldering required in this project, since all

This instructable describes how to create a non-contact range-finder using an Arduino and an HC-SR04 ultrasonic module to measure distances in the range 2cm – 400cm. The accuracy is typically +/- 3mm depending on distance, air temperature, and humidity. Step 1: Parts List Very few parts are required: 1 only HC-SR04 ultrasonic module or similar
