A board on screen
See it run, then run it for real.
Hatch draws the board and runs the student's program on it. The LED lights, the buzzer sounds, the matrix draws a heart. A student can try, fail and fix on screen, and see exactly what each change did, before the program goes onto the hardware.
In Hyper Mode, the drawn board and the real UNO R4 WiFi on the desk respond together as the program runs: the pins, servos, LED matrix, buzzer and Modulinos, with the board's own sensors and buttons feeding back into the program. Change a block, run it again, and there is no upload in between.
When the program is ready, one click puts it on the board for good.
