Circuit:
In this circuit I have used an Arduino on which I will upload the programming. Below you will find the file of the programming and 3D printer file and a mini DF player has been made on it with the help of which you can generate sound, whatever sound you want to give, I have used sound from zero to one on this and whatever programming will be done through a laser, it will be drawn by doing the programming. I have used 7 segment display and radium color has been used to draw on the board. It is a very good project, you can make it easily at home. To make it, you can learn by clicking on the video below and can also download the programming. Thank you.
