i would like to connect some arduino shields to my raspberry pi.
after some search i found 2 bridges : one from cookinghacks and alamode.
they cost between the 35 and 40 dollars ex shipping
when i search on ebay for a arduino uno it cost 11 dollars
can i use the uno as bridge and let the pi run all the scripts,
by example i hook up a nfc shield i need it to send a signal to my pi when the acces card is detected
