  • I am trying to use the the El Escudo Dos with the capacitive touch sensor MPR121, and I have hit a snag: Is there any way for me to use digital pin 2 as an interrupt pin with this sheild? I am afraid I’ll fry whatever I plug into pin 2. Can other digital pins, or analog pins for that matter, be configured and used as the IRQ pin?

    One idea is to cut the male stackable header on pin D2, in use a 90 degree pin to my bob. But I’d rather not change the El Escudo if I don’t need to.

    Any suggestions appreciated.

    On another note… Also, if I understand correctly, if I short SJ1, the EL wire will run brighter on 12V DC ? Thank you for your help. John
