/************************************************
 * BWAS - Bottle Warmer Arduino Shield Library
 * Written by Benjamin Shaya
 *
 * This library provides easy access to the hardware on the BWASnano:
 *  - 8x thermistors, multiplex through a MC74HC4051ADG
 *  - 2x High power PWM outputs with ACS715 Current Sensing
 *  - 2x High Power Digital Outputs (Open Drain) with current sensing
 *  - 2x Touch Sensors (AT42QT1010)
 *  - 3x PWM LED signal outputs (for ring) 
 *
 * This library does not provide access to the TMP007 Sensor board;
 * use the Adafruit library for this.
