Let me start by pointing out that this DIY was invented by someone who was an Arduino amateur and didn’t have a programming background. Good news, right! He isn’t an electrical engineer neither a musician. He experimented and voila! Although you do need the determination and a few skills like drafting or soldering. You can always learn these things, so let’s get started.
So this DIY is an Arduino based laser harp. It has laser beams, making sound! You can read the blog and find the inspiration behind the project. It consists of several laser beams which produce sound, when blocked. Each beam strikes a photocell and when we interrupt it, with hand, the sensor prompts an Arduino microcontroller to send a MIDI signal.
You do need quite a few things for this project. To get the complete list, read the source link. You can experiment with the enclosure design and make it as much fun as you want. But, if you want to replicate the same artefact, you can get the dimensions from the blog. Also, you can get the schematic Arduino and laser circuit diagrams to help you. And of course, complete code.
Feel free to innovate and enjoy the video
