This project was a multi-discipline project with the aim to build a christmas present for my sister. There are elements of programming, electronics and CAD involved.
A box was created that would play this song when a button was pressed through a speaker with 8Ω impedence. A disco light would also turn on at the same time, illuminating the room.
This project could not have been completed without the help of carlpilot, who 3D printed my design for the casing and aided me in debugging my early prototypes.
In order to use this code, the components used are listed below and a circuit diagram showing how to assemble can be found below.
- Arduino Uno
- PAM8302 Amplifier
- 8Ω Speaker (I used one rated for 2W)
- Disco Lights (or any other lamp rated for 5V)
- 16mm diameter button
- 5V Micro SD Card module
- Micro SD Card
- 5V one channel relay module
- Capacitor (10μF used, but 100μF would probably be better).
- Jumper wires
- 3x AA batteries to power lights.
- Power source for arduino (I used USB and 5V power adapter).
