Quiz buzzer system

Hi
I am very new to the arduino stuff. I have electronic experience but am stuck with this project.
I copied code as given (attached below) but cant get the push button to trigger immediatly.
Im using the new Unorev 3 board. could this be the problem that the code was written for the older board.
Please help!!!

How do you have your switches wire up?

Hi thanks for responding.
Connections as per link below.

please explain inconsistency in wiring

I tried your sketch with 4 switches. on my REV3 UNO

Each switch is wired +5V---Resistor----input (and to) switch---- switch----ground,

Everything works as it should.
Speed is fast.

Hi, unfortunately you have chosen to use another instructables project that has no where near enough information for you to complete the construction.
Here it fails to give you a proper complete circuit diagram.

What do you mean by

cant get the push button to trigger immediately.

Does it trigger?
Tom....... :slight_smile:

It does trigger but only after about 10 seconds if contacts are closed

Wire things up as in the image below.
The sketch will work on your Uno Rev 3

You can omit the 1K resistors if you:

pinMode(inputPins*, INPUT); // Make this an input pin.*
Change to:
pinMode(inputPins*, INPUT_PULLUP); // Make this an input pin*

Hi, Larry what CAD is that, nice and clear?
Tom...... :slight_smile:

Hi
You guys ROCK!!!
Thanks for the help getting the quiz buzzers to work.
The change in coding helped.
However....
I now would like to add a ITEAD PLAYER SHIELD to play :
Player 1...Player 2...etc when each respective button is pressed.
Please help with additional coding for attached code.
also how do i load audio to SD card.
Thanks once again for help thus far

@Tom, it's called WinQcad I think you can still download a free version from Tucows.
However, the program is no longer supported.
