#define PAUSEPLAY_BUTTON 36 // Button 2: GPIO to detect pause/play
#define MDNS_ENABLE // When enabled, you don't have to handle with ESPuino's IP-address. If hostname is set to "ESPuino", you can reach it via ESPuino.local
#define MQTT_ENABLE // Make sure to configure mqtt-server and (optionally) username+pwd
#define SHUTDOWN_IF_SD_BOOT_FAILS // Will put ESP to deepsleep if boot fails due to SD. Really recommend this if there's in battery-mode no other way to restart ESP! Interval adjustable via deepsleepTimeAfterBootFails.
#define MEASURE_BATTERY_VOLTAGE // Enables battery-measurement via GPIO (ADC) and voltage-divider
