First post - and hope its in the right place.
I am newly returned to electronics having been re-enthused by the r-pi and at the same time discovering the arduinos.
I understand the need to do logic level conversion from the RPI's 3.3v GPIO to most real projects.
Am I right in thinking I just need to do this on the data & clock (and chip-select) lines of the I2C or SPI assuming I am using either of these to talk to the rest of the project?
TIA / pibeans
