ddr/dance pads with leds and microswitch - how to wire all that !
hycday:
Hello,
I am trying to build two dance pads (for DDR-like games) with 6 clickable panels per pad. While I see many tutorials/diy/byo on internet, I saw that they are ALL outdated, or not detailed enough as per the electronic aspect for the LEDS (and also as per the system of microswitch, I still don't get how to install these under the plexi without getting them to always be pushed under the pressure/weight of the plexi... but anyway).
So for the LEDs, I was planning on getting two 5m strips band of white LEDs and cut it into 20cm bands and put 4 of them per square/panel which would give approx 80cm per panel, times 6 (up, down, left, right, and two extras), which gets me to 4.8m, per pad.
However, my question is related to how to wire all this ?
First of all, I think I can wire the bands in square, per panel with this :

but then, I need to know how to wire them :
1- with the microswitch (as I want them to light up when the microswitch is pressed). will this be a problem if the leds are 12v ?
2- with the power supply, as I would like only one power supply for all the LEDs, but not all leds lit at the same time, but only when the related microswitch is pressed. will I need resistance also ?
3-connect all that to a usb game controller to send the right command via usb
so I never really saw clear explanation on that side, so it is indeed a major stop when trying to build your own ddr pad !
by the way, if you have one nice tutorial to share, please feel free to do so !
thanks for any help/advice !

PBJ got some "Korean bootlegs from Taiwan." :dizzy: :lol
You can see some good pics in his Project Announcements thread here.

Thanks PL1 :)
well actually, I already read that thread also, but I don't got any really useful information from it. I mean technical guidance or wiring schematics or technical solutions (besides the sentence "The pushbutton is always lit when it's powered. Clicking it breaks that connection and lights the bulbs around the arrow. Yes, those are mostly 555 bulbs with wires soldered directly to them and affixed to the wood with hot glue. One 47.")
for example, I thought the microswitch needed to be power by 5v, while the led by 12v. first of all, I am right ?
here are my microswitch :

second, if that is true, then how to wire them in the same circuit !?
and besides that, how to be able to have one power supply that will lit one, two, up to six panels independently :)
is this possible ?

Hi again,
I would like to know if such a wiring (refer to picture) would work ?
would I need to add a resistance or any other components ? will there be any issue with the power supply and the leds bande length (minimum/maximum) ?
also, how would the wiring from the microswitch to the usb game controller be?
thanks again for your help !

Do you know how cherry microswitches work? They have one line that's normally closed, one that's normally open. Pressing the switch reverses that.
I used 4.5V Christmas light strings to light up the arrows, and the pushbuttons underneath have 5V LEDs in them. If you have enough LEDs in a circuit (about 20), you don't need resistors. The 5V LEDs in the pushbuttons already have resistors built in.
