Hello I was wondering if you could help me interface with the hp03d pressure sensor. Ive looked at all the other places in the forums and they don't seem to very clear on what components and libraries you need to interface with it.
When i was reading about it I found out the there is some sort of library which can generate the frequency needed to run it (32khz) on one of the arduinos pins.
Im assuming that I2c uses 5v logic? If so would I need to put a resistor in the circut to bring it down to 3v3 logic. Anyway thanks for the reply. 
So does it need the i2c signals to be brought down to 3v3?
Sorry I see it on the datasheet now.
Any way thanks for all the help.
