Will arduino uno shelds work with the arduino mega? :slight_smile:

The short answer is yes. This to the point where the Mega is not well-served in the shield department, and making do with Uno shields is the norm. I know of only one store-bought shield that is exclusive to the Mega and there aren't too many proto shields either. There a a few pin-use differences between Uno and Mega. In the case of the SPI bus, shields typically use pins that are common to both. I guess a shield using the I2C bus has jumpers and flying leads to get round the differences. Other shields may also include adaptations.

so would i have to change any of the coding to get the sheld(s) to work with the mega insead of the uno?

If you insist on talking in generalities, yes.
