Hi, I want 8 buttons. When a button is pressed, a different sound (mp3) and light (led) show happens.
I bought these parts:
LEDs: a BlinkM MaxM and LED Strip (http://thingm.com/products/blinkm-maxm.html) - ok
MP3s: a SeeedStudios Music shield (http://www.seeedstudio.com/wiki/Music_Shield) - ok
Buttons: a custom board - ok
Problem became too many parts and connections (It’s my first project)
I got an Arduino protoshield (http://arduino.cc/en/Main/ArduinoProtoShield) to help share the pins (Music Shield plugs into all pins, and I need some for LED and buttons)
So I got the Protoshield to make a sandwich: Arduino UNO, Protoshield, Music shield. With BlinkM and Switches on the protoshield.
BUT, the problem is the Protoshield’s SPI header does not go all the way “up” into the Music Shield. Without SPI, the Music Shield doesn’t work.
Thanks in advance! Mike
