We’re used to Hall effect devices as proximity sensors in mechanical systems, used to provide detection of something that has a magnet attached to it. However it’s easy to forget that the devices that provide a magnet-or-not digital output are only part of the story, and linear Hall effect devices provide a handy way to […]

This was my project for Hack Sioux Falls. I built it one weekend and it turned out a lot different than I thought it would. It was a lot of fun and there are a lot of variations on what you could have the Arduino code do once you get the shadowbox wired up. My

This instructable explains how to pinpoint the location of an object using an Arduino, two ultrasonic sensors, and Heron’s formula for triangles. There are no moving parts. Heron’s formula allows you to calculate the area of any triangle for which all sides are known. Once you know the area of a triangle, you are then

WHAT? Hi! I’ve made bleeding LED stairs! It’s a new Instructables leveraging some hardware installation I had done already from a previous I’ble from mine. I made a RED animation that resembles blood drops, perfect to be activated automatic during those trick or treat moments! As soon as you approach the stairs “drops of blood”

If you are interested in artificial intelligence and gesture recognition you may be interested in a new article published to the official Arduino blog this week by the Arduino Team. Using a Arduino Nano 33 BLE Sense and untethered gesture recognition controller has been created using the boards 9-axis motion sensor. When a button is

The official Arduino team have this week announced the launch and availability of their new Arduino Edge Control board priced at $169 or $199. Designed to provide you with a remote monitoring and control solution, optimized for outdoor environments, the board can collect real-time data from smart sensors and leverage AI on the edge. The
Arduino Edge Control board launches from €169 Continue Reading
This instructable describes how to make an ultrasonic “radar-style” display using an Arduino microcontroller, an ultrasonic sensor, and a small stepping motor. An optional sensor modification allows multiple objects to be detected with each ping. Construction is simple … all you need are two drills, a sharp knife, a pair of side-cutters , and a
Acoustic Radar Display Continue Reading
While humans have done a pretty good job of figuring out how to fly with various mechanical contrivances, the fact remains that our natural senses aren’t really well suited to being off the ground. For example, unless you have a visual reference point, determining which way is up is quite a bit harder than you

During my high-school sophomore year, the 3rd floor of our house lighted on fire due to a short circuit. Fortunately, my family was away on vacation for Christmas. But if we were home, wouldn’t it be crucial to tell the direction of fire quickly so that we know the direction to evacuate? Consider another situation.
In this post, we will learn How to Build Your Own Anemometer Using Reed Switches, Hall Effect Sensor and Some Scraps on Nodemcu. Since I started with the studies of Arduino and the Maker Culture I have liked to build useful devices using junk and scrap pieces such as bottle caps, pieces of PVC, drink
