I have a project that uses a OLED 16 x 2 Newhaven OLED, a piezo switch and I would like to add a TMP36 temperature sensor. The problem is these are remote from the Sanguino and the cable that connects them does not have a spare wire for the temp sense output. Can I just hook it up to a wire shared…

Can I use a port to run a OLED and read a temperature sensor?
