Barmband is a wearable wristband designed to gamify social interactions. The concept is driven by the often daunting task of starting conversations in bars and pubs, where socialising is the lifeblood. Barmband offers an innovative solution - a fun, engaging tool that acts as an icebreaker in these social environments.

Graphical messaging and communication overview
In order to run the application, you need to have a MQTT broker running. You can use the compose.yml file in the broker directory to run a local MQTT broker. The broker is responsible for receiving messages from the clients and forwarding them to the appropriate subscribers. After running the broker, you have to configure the application to use the correct IP address and port of the broker. Adjust the MQTT_HOST and MQTT_PORT in include/config.h accordingly. The default port is 1883. The IP address of the broker depends on your network configuration. If you are running the broker on the same machine as the application, you can use localhost.
Of course, you can also use a remote MQTT broker.
The application uses the ESP32 WiFi module. You have to configure the WiFi module to connect to your WiFi network. Adjust the WIFI_SSID and WIFI_PASSWORD in include/config.h accordingly.
Configuration is done in include/config.h.
See include/config_example.h.
