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

Let’s learn how to read a potentiometer, a type of rotating variable resistor, using Arduino’s analog input! We’ll connect up a simple circuit using a solderless breadboard and use some simple Arduino code to control a single LED. So far you’ve learned to control LEDs with Arduino’s output, and you learned to detect a pushbutton’s state (on

In this instructable we will use a potentiometer on an Arduino Uno to control a MIDI CC in Ableton Live. A MIDI CC stands for Continuous Controller, i.e. a number in the range from 0 to 127 inclusive to modulate something with. In the youtube I made for this intro you can see and hear that we

In this project, we are going to build an automatic irrigation system using Arduino which senses the moisture of the soil and opens or closes the valve according to the moisture value. The moisture value and the valve status is shown on the Nokia 5110 LCD display. Before we proceed, let’s take a look at

In this article, we are publishing a project which explains different aspects of Arduino-Gear motor interface. Gear motor is a specially designed DC motor whose gear assembly helps in increasing the torque and reducing the speed. Compared to a normal DC motor, maximum rpm a gear motor can produce is less. But they have the

This project is about how to make a time machine! This machine looks like a glove, and can “stop” any moving subject. At first, watch a video with some demonstration and experiments, guess how it works, and then read about how to make it =) This effect looks like better in real life (by naked
