Hello, i got problem with delay, I tried different ways but none of them work. Please help

You have to understand the concept of asynchronous processing

Hello, thanks for feedback again Taifun. I read that, but im too bad at programming so i didnt understand this posts :c. I used ur wait method btw

Use a Clock Timer.

Start the Clock at the place where you called that wait procedure.

Move the code you had under the (now deleted) wait procedure call to the Clock1.Timer event.

[ScottFromScott]

Put these blocks inside your Clock1.Timer event block instead. Then execution continues from there.

Hello, thanks ScottFromScott. I'll try it

Hello ABG, thank you. I'll try it

Hi, its not working too

You realize this is replacing the same target list 4 times, right?

[ABG]

You totally missed the point of the Clock Timer.

You're supposed to do work in the Clock Timer.

This is what you created:

Need help on a delay and 3x repeat for Arduino Bluetooth

Your app's timing technique could follow the timing technique of this Morse code player: Use your own coding instead of Morse. Send BlueTooth messages instead of vibrating the phone.

Study the clock in this sample.
