EV3 programming... hit twice left arrow and then ...

[Bumblebee]

Hello,

My son want to hit twice the left button to start a motor. Is it possible to program that? I try, but im not good.  I can do it with 1 hit on the button, but i don't know what to use for wait for 2 hits.

Can someone help me ?

Thanks.

Simplest idea might be doing the condition twice (duplicating the condition you currently have).

Recommend reviewing the "Loop" and "Switch" guidance on EV3Lessons.com .

Create a new variable set to 0. Inside a loop which reads the variable and ends if the variable = 2 put a switch block. If the switch detects the left button is pressed, read the variable block, add +1 then write back to the variable. The other option on the switch is set to default but is empty. Add a sound block after the loop for testing. You might need to put a wait block after the switch inside the loop set to 0.1 seconds.

Here is a much simpler way:

(wait for button press)-(wait for button release)-(wait for button press)-(start motor)

Easy!

If you want I can make the program for you.
