2 boards, same digital pins.

Hey everyone,

I understand there are complications using 2 boards that use the same digital pins? Is there any way around this?

Thanks in advance

Do you mean 2 shields in the same Arduino?

Depending on the protocol those shields use, it is possible for them to share the same pins. For example: I2C devices use the same pins, even although they can be in different shields or even not in shields. The same is true for devices communicating over SPI.

Now, if the devices or shields don’t use any of the “cascading” protocols, then you are out of luck.

... that is if this shield can not help you out https://www.sparkfun.com/products/11002 Best regards Jantje
