/*  1111 - The Arduino Node Sketch
 *  From Raspberry Pi Full Stack Raspbian
 *  https://app.techexplorations.com/courses/raspberry-pi-full-stack-raspbian/ 
 * 
 *  This sketch allows an Arduino to transmit DHT22 data to the Raspberry Pi
 *  base node, using the nRF24 transceiver.
 *  The sketch places the Arduino in low-power mode when it is not doing 
 *  useful work.
