HC-020K Encoder Module Guide

This HC-020K encoder is very useful to sense the motor’s position and velocity. It can be connected to any microcontroller via the 3-pin header. In this article, we'll talk about how to wire and set up the module for operation with an Arduino Board.  Wiring Most HC-020K modules operate with 5V and produce a digital output within the range of 0V to 5V. It will provide a 5V output when the beam is blocked, and a 0V output when the beam is unblocked. Arduino can read the pulse train to determine how far the motor has travelled at what velocity. For...

ACS712 Current Sensor Module Learn Guide

The ACS712 Current Sensor module is a very popular module for measuring the current applied in the circuit due to its capabilities and its price.  In this article, we will talk about how to wire and set up the module for operation with an Arduino Board.  Wiring  Most ACS712 modules operate at 5V and produce an analog voltage output proportional to the measured current. For this project, we use a power supply (giving output voltage from 0 to 5V), and a resistor to generate current from 0 to 5 A. There are a few versions of the ACS712 Module in the market, but...

SW-420 Vibration Sensor Guide

The SW-420 Vibration Sensor Module is a useful module for detecting vibrations over a threshold point and provide digital data, 0 or 1. It uses an LM393 comparator to detect and it can work from 3.3V to 5V.  In this article, we'll talk about how to wire and set up the module for operation with an Arduino Board.  Wiring This module can work from 3.3V to 5V. In this project, we will use 5V to power the module. During normal operation, the sensor provides Logic Low and when the vibration is detected, the sensor provides Logic High. There are several...

SW-18015P Motion Vibration Sensor Module Learn Guide

The SW-18015P Motion Vibration Sensor Module is a small spring inside the metal casing. As the sensor vibrates or moves, the spring will make contact with the metal casing and conduct through the sensor. This module is an easy sensor to use with an Arduino Board. One of the benefits is that you can access both analogue and digital signals. In this article, we'll talk about how to wire and set up the module for operation with an Arduino Board.  Wiring This module can work from 3.3V to 5V. In this project, we will use 5V to power the module. This module...

Project 3: Music Box

Posted by Rhiannon L on

Project 3: Music Box
Today, you’ll learn to program something your Arduino to play a tune when you press the button! This project uses a buzzer, which is a small piece of technology that makes a little "click" when you apply voltage to it. If you turn the voltage on and off hundreds of times a second, the buzzer will produce a tone, and if you string together a bunch of tones, you've got music!
