Hi everyone,


Has anyone connected the GPIO to a relay in order to control 110VAC devices (such a light bulb)?


I did take a look at the email-archive, and from what I understood one cannot connect the GPIO pin directly to the relay. Instead, a transistor must be used between the relay and the GPIO pin. (ref: http://sourceforge.net/mailarchive/message.php?msg_id=10129129)


Would be happy to hear any experience with relays or any word of wisdom that anyone could share with me on this matter.


Thanks everyone,
