Last time I went looking for a relay to run with a pic, I ended up using a solid state relay because the mechanical relays needed more drive current than the pic could do directly. Of course, I limited my selection to whatever was listed in Digikey. So, does a solid state relay count as "real"? -- http://www.piclist.com hint: The PICList is archived three different ways.
