The JARU IDE Music Tracker lets you compose your game's music without leaving the environment, just like code or sprites. This tutorial walks through the whole process with screenshots: start from a template, type notes into the grid, tweak an instrument, listen to the result, and leave it ready for your program to play.
This tutorial focuses on the graphical side of JARU: opening a screen, preparing a drawing surface, and building a small interface with the Display and Draw modules: text, cards, status bars, rectangles and circles.
The first step in the hardware world is always to blink an LED. In this tutorial you will learn the basic syntax of JARU and discover one of its best features: write the code once and test it both in the Windows simulator and on your physical ESP32 board.
After blinking an LED, the next natural step is reading the outside world. In this tutorial you will learn how to connect a push button, read its state with GPIO.read, and finally react to presses using interrupts — all tested first in the Windows simulator and then on your physical ESP32.
