+ * \section SSec_Description Project Description:
+ *
+ * Firmware for a Teensy2++ AVR-based miniboard to control four relays, using the
+ * same protocol used by the commercially available Silver Shield PM power outlets
+ * ( http://sourceforge.net/projects/sispmctl ) sold for some time. Because this
+ * project mimics the original device, it can be controlled using the "sismpctl"
+ * package included in many Linux distributions - including router-orientated
+ * versions such as OpenWRT - to control the board's relays.
+ *
+ * Relays 1 to 4 are respectively wired to pins C4, C5, C6 and C7 of the Teensy++ V2,
+ * which are the PORTC bits 4 to 7 of the AT90USB1286. The relays MUST be wired through
+ * a transistor, and a diode must be added on the relay's contact pins to protect
+ * the transistor from back EMF generated from the relay when the coil is turned off.
+ * The transistor base pin is wired to the Teensy data port through a 10K resistor. A
+ * LED may be also be added as a relay status indicator on each channel.
+ *
+ * The Relay coil will be driven by the transistor, but the power will come from
+ * the 5V from the PC's USB port: Be careful in choosing the relay to avoid overloading
+ * the PC, as the maximum current used MUST remains under ~450mA @ 5V.
+ *
+ * The author's tested relays are 2 Finder 32.21.7.005.2000, coil il 125ohm, which can
+ * handle 5A @ 250VAC. Be careful to use proper isolation if high voltages are manipulated.
+ * The author used Hotglue to isolate all parts of the PCB in contact with high voltage.
+ *
+ * See <a>http://www.pjrc.com/teensy/</a> for the Teensy2++ website.
