FEEL THE FORCE WITH A POCKET MAGNETOMETER

With the rise of affordable 3D printers, we just don’t see the projects in Tic Tac boxes that we used to. That’s kind of a shame. Not only are you upcycling existing plastic when you use one, they’re decently sized component vessels for pocket builds such as [rgco]’s portable magnetometer, especially if you can get the 100-count box. Best of all, they’re see-through! Sure, you could get a magnetometer app f ...

Arduino distance meter with Ultrasonic Sensor (HC SR04) and Nokia 5110 LCD display

Introduction Measuring distance is so important in today’s world that things like driverless cars will be impossible without it, that description is probably enough to describe how important knowing the distance between two objects can be. For that reason, today we will be building a distance meter using the Arduino and the HC-SR04 ultrasonic sensor. The HC-SR04 ultrasonic sensor is a cheap ranging sensor c ...

Arduino for Nerf: Ballistic Chronograph

Arduino is an amazing tool for Makers, and as I got back into Nerf and started modding, I began to wonder what I could do with Arduindo to help determine the effect of modifications. Take a look at any older Nerf video and you will find a kid firing darts on their lawn over a tape measure. Take a look at any recent Nerf video, and you will see them shooting darts through an expensive ballistic chronograph. ...

How to Use Water Flow Sensor – Arduino Tutorial

In this tutorial you will learn how to use one water flow sensor with an Arduino board. The water flow sensor consists of a plastic valve body, a water rotor and a hall-effect sensor. When the water flows through the rotor, rotor rolls and the speed of it changes with a different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This type of sensor can be found on different diamet ...

Arduino UV Meter using the UV30A Ultraviolet Sensor

Introduction Ultraviolet rays, also known as UV for short are rays emitted by sun. Due to the depletion of the ozone layer, these rays tend to get to extreme levels that could lead to sunburns etc for those under it, that’s why daily and hourly forecast of the UV index is always available to help people keep track and stay safe. For monitoring purposes, why not own a personal UV meter? Today, we will build ...
