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 […]

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

Let’s learn to sense movement in a room with a PIR motion sensor and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. We’ll use Tinkercad Circuits to simulate the circuit so you can follow along even without any components, and show

Let’s learn how to read a photoresistor, a light-sensitive type of variable resistor, using Arduino’s Analog Input. It’s also called an LDR (light-dependent resistor). So far you’ve already learned to control LEDs with Arduino’s analog output, and to read a potentiometer, which is another type of variable resistor, so we’ll build on those skills in this lesson.

Let’s measure distances with an ultrasonic rangefinder (distance sensor) and Arduino’s digital input. We’ll connect up a circuit using a breadboard and use some simple Arduino code to control a single LED. You may have already learned to read a pushbutton and PIR motion sensor with Arduino’s digital input, and we’ll build on those skills in this lesson. Ultrasonic

Calculating on paper is never an easy job. And when it comes to formulas with sub-formulas of their own, it is nothing short of a nightmare! Take the case of a simple pendulum, which has a variable with a formula of its own. What if there was a way to replace these scary calculations with

Ultrasound ranging is a complicated task that made easy by the readily available module for Arduino. To detect or measure the distance it transmits the signal to the target and target reflects that back. Arduino measure time is taken for complete travel. As the speed of sound is known the distance in between module and

In this project, We’ll try to get some information from the human body by using simple sensors and Arduino. You can use this information to create a lie detector machine. At the end of this article, you : Know Polygraph and basics of measuring and recording physiological indicators. Will be familiar with Lie Detector systems.

In this tutorial we’re going to play with a gesture sensor (APDS-9960) and a neopixel ring to learn how to combine them both using an Arduino UNO. The end product will respond to left – right gestures by animating led movement right or left, and to up-down gestures by changing leds color. In the next
