I am new to the world of Arduino. I worked in the haunted house industry and used Picaboo controllers for a few years but they have limitations. I am building an aztec-themed piano prop for an escape room and would like to know what equipment/electronics I would need to do the following...
1) There are eight piano keys. I am planning on using snap action switchs or small spring contact switches to send a low-voltage signal to the controller when a key is pressed down. I need eight inputs and outputs so each key when pressed can play a unique audio clip.
2) I also want to program an output (like a door opening) when a certain sequence is played on the piano.
I was planning on getting this Elegoo starter to kit to learn some of the basics. Something tells me I would need a bigger board with more inputs/outputs?
