DIY Arduino mini laser engraver from a DVD player

The YouTube channel DIY Builder has published and created a DIY Arduino laser engraver which is powered by an Arduino Nano development board and is fitted with a 200-250mW 650nm Laser Module. Check out the video below to learn more about the DIY Arduino laser engraver constructed using the innards from an old PC DVD player. A full list of all components has been provided enabling you to get everything ready ...

Arduino Touch Screen Music Player and Alarm Clock Project

In this project I will show you how you can make an Arduino Touch Screen MP3 Music Player and Alarm Clock. You can watch the following video or read the written tutorial below. If we enter the Music Player we can start playing the music by pressing the big “Play” button in the middle of the screen. Right beside it, there are two more buttons, for playing the previous or the next song. Above these buttons th ...

Arduino Project 6: Web-controlled music player

Our NetPlay project is built on a standard breadboard. In our previous Arduino masterclass we briefly introduced the Ethernet Shield an Arduino expansion board that adds Ethernet connectivity plus microSD card storage. We used that storage as the basis of a simple one-button digital audio player. It was functional but limited to 8-bit mono WAV files with a 19kHz sample rate. We also gave you the software to ...

Arduino Project 5: Digital audio player

So far in this series we’ve had a diverse look at how Arduino can interact with a range of real-world devices from servo motors to ultrasonic range finders TVs to humidity sensors. Now we’ll see if we could get the Arduino to make a few sounds. We’ll actually do a bit better than that – we’ll look at the importance of pulse width modulation (PWM) to microcontrollers by building our own digital audio player ...
