Introduction: The Door Singer
Helo everyone !
I'm in quarantine and the days are boring. So i decided to create a useless thing ... The door singer !
Ok ... I know ... It's useless ... But it's fun !
The goal is that when someone open the door, it make sound (customizable sound) like a fart, a shouts, a music ... (i warned you ... It's useless)
Because of quarantine, I could not buy what I wanted in store. So i did with what i had :)
I've used the following material :
- Raspberry Pi 3
- Limit switch (I was able to find one in an old PC)
- A little speaker (I found what I needed in an old box)
- Wire , and a thing to connect your speaker to your Raspberry Pi
That's all !
Step 1: Color of the Wires in the Jack Cable
My jack plug wad broken. So i need to reconnect a new male jack in the speaker.
I found an old pair of headphones (Samsung maybe) and i identify the wire color and associated then to with their functions.
(like in the picture above)
I didn't have a heat shrink tubing ... So i've made with tape.
Step 2: Codding !
I've connected my button (normaly closed - NC) to the pin 1 (+5V) and the pin 7 (GPIO) of my Rpi.
So now i'll code what i want. For this project i used Python (but u can use other boring codes to do this)
In short :
- Pygame is used for playing a sound
- Time is used for give the CPU a chance to do additional task
- GPIO is used for listen to what happening on the GPIO output (obvius)
I left you my code as an attachment <3
(You must have the sound played in the same folder as the code)
Step 3: Fix Everything ! and Let's Test !
I fixed the button to the door as the best i could (with tape).
I connected all the wires ...
And open the door :)
Step 4: That's All !
