Just started wiring stuff up and testing. Is there a way to use two screens; one for Hengstler and the other in the scope?

Hello! I'm almost at this point with my build. I have almost everything to star testing, but i have some doubts. Im using the same components as you are in this picture, do you need to solder any resistors? If yes, which one and where?
Thanks-

Hi,
First off, you do not need this charger circuit. I also cannot tell you if it's going to work with it. But with 5V your neopixel stripes will draw a lot of current, what you do not want. Stay with the 3.7V of the Li-Ion, you do not need more.
OLED you can pick one of them. With multiple circuits both could be enabled for sure.
A magnetic switch is actually nothing else than two pieces of magnets, one connected to a GND signal, the other to a digital input on the board. If you short these two magnets with a ferromagnetic material (i.e. piece of iron/steel for instance), it acts like a normal switch plus the magnets will hold the part which is attached to the ferromagnetic material in place (provided it's not too heavy and/or the magnets are strong enough). That's it.
And the neopixel stick is just an option, you can take any stripe or even leave it. Actually you should at least have one pixel, even a single one at the front of the nozzle, all the rest is up to you. You can configure the split between the barrel-nozzle and status bar in the menu. Both of them can be set to 0, in which case that segment will not be illuminated.
I'm gonna stick with the 3.7v out of the charger then, not step-up.
I'm still unsure whether i'll install the magnetic switch or not, it depends on how much i will be able to do in terms of coding.
My blaster will gave a neopixel flora on the front and double led strip on the barrel.My question was regarding the "Neopixel Stick (for PLI/Status bar)". I want to understand the point of it and if it's a "must have" part.

Dear Swornhill,
Wow, you really mean to build one!
I have some doubts about the following items:
- Battery charger/step-up for charging the battery and convert power to 5v
Not sure what you intend to achieve with it. You can have a recharge port where you can charge your Li-Ion with a dedicated charger, but to use a DC-DC you need to be careful. I can help you if you provide me with a wiring diagram of the modifications you plan.
- PAM8403 stereo amplifier because i want 2 speakers
Never tried this, but it sounds certainly interesting. Keep us in the loop, if it works I can add it as an alternative way of wiring it up.Now to your questions:
- I'd like to know if I can add a second OLED on the scope with this setup.
You can use only one OLED: either the 128x32 as a status bar or a smaller one 64x44 for the scope. Not both. The Atmega328 does not have that much memory to support multiple displays.
- I want to add a aux switch to change modes and a magnetic switch on the magazine for the reload sound, can I do both?
This should be possible and I already had one blaster where I did just that. However lately I did not check that branch of the code. Please try out and if you face difficulties, let me know and we can make that somehow stale branch back on line.- Can i run 2 LED strips on the barrel? My model has a inner barrel and i wanted to glue one strip on each side. Can the arduino run both strips?
Sure, this is how all lightsaber props work with neopixel. You simply connect the BAT+, the GND and the data line to both strips in parallel.
Good luck!
Thank you so much for the help!
About the battery charger, I thought i needed a module just for charging the battery and make the output 5v intead of 3.7v, something like this:About the stereo amp, more speakers, more volume! It seems easy to install, i'll post about it in a few months when i have all the parts (we know what happens with stuff coming from china, it's not quick)
About the OLED, I've seen some blaster on youtube with both but probably have the scope display on a separate circuit?
I want to know more about the magnetic switch because it's a cool feature but i need the right parts.About the strips, that's what I thought.
Actually, I have another question. Is the neopixel stick really necessary? because i see it hidden on the "bullet chamber" most of the times.Thanks!

Good evening! This is my first post, so hi everyone! I hope all of you are safe in these troubled times.
I completely new to blaster building but i'm a fast learner.
I just started 3D printing a E11 blaster. It's a replica designed to receive electronics and i decided to go with the Arduino version.I understand that these items are all I need:
- Arduino Board (Atmega 328P)
- DFPlayer module
- WS2812 stick
- RGB neopixel flora
- Microwitch with long hinge
- Li-on battery and holder
- Battery charger/step-up for charging the battery and convert power to 5v
- PAM8403 stereo amplifier because i want 2 speakers
- 2x 2w speakers- 0.91" OLED display
- wires and JST plugs
- main switch
- usb plug for charging only
And now I need some help with the last three items
- Can i run 2 LED strips on the barrel? My model has a inner barrel and i wanted to glue one strip on each side. Can the arduino run both strips?
- I want to add a aux switch to change modes and a magnetic switch on the magazine for the reload sound, can I do both?
- I'd like to know if I can add a second OLED on the scope with this setup.This will be a fun build.
Thank you in advance

Happy with your reply, I am, hmm.
So, no resistors? not even between arduino and switches? Because I see pcb boards (aka carriers?) with resistors pre-soldered.
Thanks!
