- * What it does:
- *
- *
- */
-
- /*
- *
- *
- *
- * Directions:
- *
- * Use Arduino Uno
- * Connect Pin 3 to Reset pin (may not be needed)
- * Connect ENC28J60 using these instructions:
- * https://github.com/ntruchsess/arduino_uip
- * http://web.archive.org/save/https://create.arduino.cc/projecthub/Sourcery/how-to-connect-the-enc28j60-to-an-arduino-efd0dd
- * CS for ENC and UIP library is 10 by default on UNO. Not 8, like that link says.
- *
- * Connect microwave motion sensor such as HB100, or laser diode to A1
- * Add a speaker for audible debugging
- * LED can also be added
- *
