Quiz Show Buzzer System using Staples Easy Button

Step 6 Wiring the Unit

First screw in the battery holder and connect the wires to the circuit board (Photo 1).

Next we are going to connect the LEDs to the circuit board. Pay attention to positive/negative (which is why I used two different colors). I added heat-shrink tubing up near the lid to prevent wire contact. I also put a dab of hot glue on the circuit board for the same reason (Photo 2).

Run your easy button wires through the holes in the box and connect them to the board as shown in the picture (Photo 3). This is kind of a pain because of everything being connected.

Finally, attached the slide switch wires to the upper left corner of the board (Photo 4). See the kit instruction for more details on the holes to use. This is done last to make it easier to solder the button wires.

(Note: all wires are soldered on the underside of the board)

I can't quite tell from the pictures where the slide switch wires attach to the circuit board.  You indicate they go to the upper left hand corner and advise to  refer to the circuit board instructions, but I'm still having trouble.  Do you have another picture or more specific instructions?  Thank you.

In case you haven't figured it out yourself or someone else had answered your question, here is the answer. There are are three holes next to the battery where the tiny slide button supplied withe the kit goes. You need to use the two holes closer to the battery connection to connect your larger push button.

Thanks for the great instructable!!
This should save a whole lot of arguments over who rung in first at my youth group.
And at an affordable price too.

i have a question regarding the circuit, i built the circuit exactly as you said but it seems like no electricity is running through the circuit because my LED lights are not going on. What are some of the possible problems that i could have? i was thinking it was my soldering but im not sure.

LED's might be backwards, power might be backwards, buttons might not be functioning. Test with a multimeter in DC volts mode.

Not to mention a cold joint or two

Hi I'm Trying to make one of these for my class and i keep having a problem where my 5th LED lights up automatically when i connect my easy button is that what happened to you?
I was also wondering what type of wire specifically you used because mine doesnt seem to be working well.
Thank you

Hi,

I used braided copper wire for most of the project, solid for some short connections. Have you used a multimeter to make sure the problem is the wire itself and not the soldered connections?

As for the 5th LED issue, I'm not quite sure what to say because I didn't use that LED (just the switch) and didn't have an Easy Button connected there, but the momentary switch instead. That slot isn't meant to serve as a 5th "player" if that's what you were trying.

Speaking of 5th players:

On the left side of the board, there are 3 holes, labeled "1,2,3". You can make this an 8 player buzzer system by connected 1 2 and 3 from this board to another board. (The board says that in the middle). so, technically, you can have a 1-8 buzzer system.

ok thank you I fixed the problem I took out the LED and checked the connections and everything is working great now thanks again
