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

This is a trap to capture the mice without hurting them, so you can release them outside. If the proximity sensor detects the mouse, the Servo motor will close the door. You will receive an instant message and/or an Email, to inform you that you captured a mouse. When you are not at home or

Recently, I came across RDA5807 module which is an FM Radio Tuner in a very tiny package. It is very cheap and uses I2C protocol for communication which means that only two wires will be required to talk to the IC. Less wiring! My mom used to listen to the radio every day while cooking food before
My hobby and passion is to realize physics projects. One of my last work is about ultrasonic sonography. As always I tried to make it as simple as possible with parts you can get on ebay or aliexpress. So let’s take a look how far I can go with my simple items… I was inspired

Charlieplexing. Aside from being a fancy word it is a technique for driving multiple LEDs with relatively few pins on a microcontroller. It allows you to drive N*(N-1) LEDs with just N pins without requiring any additional hardware, making it a quick, cheap and easy way to add multiple LEDs to your arduino projects. Throughout

Description Hey everyone What’s up! Let me show you something COOL! A completely 3D Printed Mini Air Cooler that is powered by a Jet Turbine. So the goal here was to make a small but powerful Air Cooler that utilizes water to cool down air that is fed by a Jet Turbine. In this post, I’m going

The last couple of years I started learning about electronics from nothing to be able to build my own MIDI controllers that would serve my needs , taste and be cheaper overall in comparison with the branded products.This is CRIUS ROT8 MIDI CONTROLLER that consists of 8 potentiometers and 3 buttons with which we can

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

There’s a lot of night lamps outside, but they can’t customize to your favorite color. So, this project is to make a night lamp that you can choose your favorite color. Step 1: Step One: Electronics Needed Here are the electronics you need to make the Decoration. 1. 2* Arduino buttons 6*6*5 mm Purchase here 2.
