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