2  Arduino Plug and Make Kit All-Modulino Demo
3
4  This sketch initializes various Modulino components, including buttons, buzzer,
5  addressable RGB LEDs, encoder, distance sensor, IMU (Inertial Measurement Unit), thermometer,
6  and an LED matrix. The system performs the following tasks:
7
8  - Plays a sequence of musical notes with corresponding LED animations on startup.
9  - Continuously reads and outputs IMU data, temperature, humidity, distance,
10    and encoder position to the Serial Monitor.
11  - Controls the LEDs and buzzer based on button presses, allowing for interactive
12    feedback.
13
14  The heart pattern is displayed on the LED matrix upon initialization.
15
16  Compatibility:
17  - This code is designed to work with the Modulino system components and an
18    Arduino UNO R4 WiFi.
