Thankfully, it's an easy problem to solve with an I2C-enabled device like the MCP23008 (for an extra 8 GPIO pins) or the MCP23017 (for an extra 16 GPIO pins). This tutorial will show you how you can get up and running quickly with either of these chips.<br/> <p><strong>Tags:</strong> #electronics #imported:pinboard #io #raspberrypi</p> Mon, 18 Mar 2013 05:08:28 +0000 linkding-ssg:bookmark:23491 electronics imported:pinboard io raspberrypi http://howto.opml.org/dave/editorOpmlOrg/instantOutlineTool.html#prerequesites "The Instant Outline Tool for the OPML Editor allows a group of people to communicate using an outline to reflect each person's status.
