When on board button [event]

#1

Hi @tec_support,

I’m looking at mBlock 3.3.1 on the Mac and wondering how the when on board button [event] hat block is intended to be used. The block doesn’t seem to generate any code in the Arduino IDE when I add it to the Scratch environment and there does not appear to be a way to trigger it other than directly clicking the hat block itself.

Is this a future feature that hasn’t been implemented yet or possibly it is intended for a different board?

Thanks in advance.

Hi chuckmcknight,

The when on board button [event] is only for online use, the on board button [event] can be used offline.

Greetings @tec_support,

Can you provide a sample program that uses the when on board button pressed hat block? I’ve tried several things with the mBot on the USB cable, but I can’t seem to get it to trigger.

Thanks!

Hi

Please try the following simple program, when you click on this program, then press the Button on Mcore board, you can see the RGB LED1 and RGB LED 2 will be red on.

Hi @tec_support,

The event hat blocks are usually used as a “subroutine” attached to an event. I used the following program to verify that the the code was working.

The when [green flag] clicked block is required for an event loop or nothing seems to happen.
