Last week, one of our Facebook followers asked us how to control a PIC microcontoller wirelessly.
Managing Editor Aaron Hand recommended him to read our recent Real Answers column "On the Go With HMI," that deals with this subject. Hand also refered him to a white paper from Opto 22, "Overcoming Concerns About Wireless PACs and I/O in Industrial Automation," that discusses this as well.
