I have a Adafruit music maker shield for the arduino Uno. This page shows what pins are taken up. I just want to make sure im reading this right. Im trying to figure out what pins are free to use for other things.

Adafruit pinout page.

• MCS - this is the VS1053 chip select pin, connected to Digital #7
• DCS - this is the VS1053 data select pin, connected to Digital #6
• CCS - this is the SD Card chip select pin, connected to Digital #4

"DREQ - this is the VS1053 data request interrupt pin - connected to digital #3"
--------------I am not sure if i can use digital pin 3 or not?

"SPI SCK - connected to Digital #13 (but can be connected to the ISP header with a jumper) - used by both the SD card and VS1053

• SPI MISO - connected to Digital #12 (but can be connected to the ISP header with a jumper) - used by both the SD card and VS1053
• SPI MOSI - connected to Digital #11 (but can be connected to the ISP header with a jumper) - used by both the SD card and VS1053
• As of Aug 23, 2023 - We've updated the music maker to use the 2x3 SPI header instead of pins 11/12/13"

----------So I am assuming that i can use digital digital pin 11,12,13 for other things(like buttons or turn ons) as i just got the shield a few weeks ago and i assume they rewired it or whatever so it doesnt use 11,12,13 anymore?

So assuming im reading this right. The below pins would be free to use, yes?

• Digital #0 and #1 (with caution, due to serial communication).
• Digital #2.
• Digital #5.
• Digital #8 to Digital #10.
• Digital #11 (now free).
• Digital #12 (now free).
• Digital #13 (now free).
