Can't view the second picture. It is important to see the board.
Attach your images to your post, not some other site.
But I think you will need one, two, or three Arduino pins to control the board. You will not be using the same pins to control the board as you use to light the LEDs.
I can link the photos from the first page and this post link
- the switch that controls the sounds and grill like display passes sound from speaker to pass through
- the main board that controls the light and sounds
Can you take better pics? Close-up, well-focused and well-lit? Both sides of the board. It's very hard to see what's connected to what right now.
Here's the underside of the board
and a close up of the top board - this controls the light
Ok, well... It's quite a mess. Geordie would not have approved.
The main problem I can see is that the buttons that control which sound effect is made won't work as "power up/down" buttons. If you press "power up" more than once, the circuit cannot tell that this has happened. When you press "power up" the first time, the spdt switch moves to the corresponding position. If you press "power up" a second time, nothing happens because the spdt switch has already moved. Do you understand what I am saying? Do you have a plan to fix this?

I'm just gonna hot wire the sound that I need unless use the arudino to play a tone at pin 13 and just use the sound board to light up the LED (changing it to a super bright 5mm red one) and fire the Stun sound only.
the way how playmates put that switch is three wires so if it's on the right of the 2nd button
like this if the switch on the left it play sound 2 and if it's on the right it plays sound 1
left uses white and brown wires while on the right of the switch uses blue and brown.
the way I'm doing it is removing the switch and replace the switch with momentary pushbuttons so each button powers the display up or down. like left goes up and right goes down (like the real TV show prop)
Ok. First you should draw a schematic showing all the components. Hand drawn on paper is ok.
Then you should build the whole circuit on breadboard for testing.
as far I can do is use this but can't get it in fritzing for the schematic view right as it's gonna be a jumbled mess
I could try doing breadboard shot if that can help - I just need to multiplex 16 leds to become the power display
Star Trek: TNG Phaser Mod - Electronics - YouTube - here's a video of one user did to make their on power display it shows the main soundboard (as a redboard) in conjuction with the arudino's prototype for his display.
If you do it well, the Fritzing schematic view will be better and clearer than the breadboard view. In a schematic view, you don't have to follow the physical layout, you can move things around so that they are less jumbled. It also helps if you use the GND and Vbat symbols everywhere you need them so you don't have to have wires for them.
How do I show the multiplexed LEDS within' the Arudino Uno (used for mini if I can use it instead) and work on a way to get it with NPN and stuff I may have to get a LED Driver chip to control all 16 Leds in a line.
How many pins do you have to drive the LEDs?
You need to work out how many you can dedicate to the LEDs.
If not using a driver chip, you will need at least 5 pins and 4 npn transistors. But this requires charlieplexing and is complicated.
Or you can use 8 pins and 4 npn transistors, or 10 pins and 2 npn transistors. This would be using normal multiplexing and a little simpler.
I need to power all 16 LEDs and each one turns on to indicate a level of power much like the way the phaser works when I press the left button.
I could use a 16 or 8 pin LED driver so I can shift register them all on so I feels like a power level I'm after.
trying to keep the prototype small so it fits inside the toy's limited space and with wires on my separate circuit for the power level display.
Ok, I'm trying to give suggestions and ask questions that you need to think about in your design. But you just keep repeating yourself and I don't see you putting in any effort yet. Perhaps you don't understand what I'm saying or asking. If so, please ask me to clarify. Perhaps you are waiting for me to present you with ready-made schematics and code. That's not how it works around here.
I hope to see some progress from you.
That's NOT what I'm asking for I'm working if I should get the led driver of either 8-pin or 16-pin I'm doing it simple and small
This led display I've done shows what I need to do with either npn or led drivers - I have to keep them all on every time I step it up.
It's also close to each other which is harder to drive them using npn transistors
