Arduino Magnetometer

Arduino Magnetometer

What are we building? Humans can’t detect magnetic fields, but we use devices that rely on magnets all the time. Motors, compasses, rotation sensors, and wind turbines, for example, all require magnets for operation. This tutorial describes how to build an Arduino based magnetometer that senses magnetic field using three Hall effect sensors. The magnetic

Arduino Fireflies

Arduino Fireflies

One of the things I look forward to with summers in Pennsylvania are fireflies in my backyard. I recently taught myself Adruino programming for the purpose of making this simple project. It’s a great program to start with and is easy enough for any programmer, novice to expert, to build, modify and have fun with

ARDUINO PH METER

ARDUINO PH METER

In this project, we will be making a benchtop pH meter using the gravity analog pH circuit and probe from Atlas Scientific and an Arduino Uno. Readings will be displayed on a liquid crystal display (LCD). MATERIALS 1 – Arduino Uno 1 – Gravity analog pH sensor 1 – pH probe 1 – 20×4 LCD module 1 – 158x90x60mm Enclosure

Upright Laser Harp

Upright Laser Harp

Laser harps are musical devices with laser beam “strings.” When the beam is blocked, a note is played by the instrument. Usually laser harps have the beams travel vertically in the shape of a fan or vertical lines. In this project, I built a laser harp with stacked laser beams that propagate horizontally. The beams
