Generic Electronic Appliance Remote Control

It is comprised of S9KEAZN8AMTG Freescale Kinetis E 32-bit MCU that controls the triggering of the reed relays, and the transmission and reception of signals through the xBee RF module. The triggering signals are with pull-ups to ensure the switching of relays will take place. The general purpose diodes in series are for the protection of the MCU pins while the diodes in parallel are protection for blowback voltage.

This design is applicable to different electronic appliances and some of the industrial instrumentation devices. It offers convenience to remote control interfacing between electronic devices and it can still be modified to optimize its applications.
