#ARDUINO BUTTON PRESS SERIAL#

and that is why i wanted help understanding this function, I am not getting much help from internet or youtube videos. My teacher suggested me to use the millis() function but he never taught that.

#ARDUINO BUTTON PRESS SERIAL#

I want to display on the Serial monitor, how much time people waited in each area. I let in 3 people (so after 3 button presses) from the first door, and then close all the doors, and after a certain delay I open the second door to move the people in the next area, and again close the door. Hi everyone I started programming in arduino a little while ago and I now have a problem that I can not overcome: I wanted some function that when i turn on a button the arduino press the letter 'D' and waited until the button was turned off and typed 'D' again. Double presses are little harder, because you have to delay the signaling of the short press, if it is followed (again compare the times of the events) directly by another short press. I can let in 3 people in through the door, and I am simulating this with the button press. Take the time at button press and the time at button release, decide on the difference whether that should be a short or long click.

When button is pressed 12V - on the left side of the button 0V. A press is the equivalent of clicking and continuously holding the mouse button. I am very new to millis() function, and that is why having problem integrating it into the program I mentioned above.īasically what I have to do is: I have three doors, which I am simulating with 3 red LEDs, when any LED is on means that the door is closed, and when any LED is off means that the door is open. Here are the results I got from what you asked me to do: With COM on Battery-Negative and the other lead: - on the right side of the button 12V. Sends a button press to a connected computer. When the button is pressed, there will be a connection between all of the legs.

I followed what you said about the Bounce2 library, but instead of using that I wrote a button state detection code. A pushbutton really only has two connections, even though it has four legs. I have read it, but I am still so confused about the millis(), I have literally searched everywhere, but it doesn't seem to solve my issue, the maximum i am getting is finding the elapsed time.
