Hi! I did have a thread on this but accidentally closed it 😅 I'm trying to add 2 batteries to this setup using neopixel jewels and arduino. I'm using Tinkercad to trial and test but am a little confused as to why I cannot wire the batteries correctly? I've attached some images, one with the complete setup with lights on, and the 2nd photo with my attempt to add batteries, but when I run it, the lights do not light up. Any assistance would be really appreciated

Top photo is the working circuit and below doesn't. I wanna attach separate power supplies to the board and lights to prevent burn out

You need to attach the ground side of both power supplies together.
Keep the positive of Both Power supplies separate

Like this? Is this safe and won't burn out the lights?
Also thanks for responding! 🙏

No , not quite
Also , you should rethink the colors of the wiring you are choosing in your diagram. When working on electronics and with most engineers, certain colors generally represent certain things. If you pick random colors it can be confusing when talking to others and asking for help.
Normally:
Red - this is generally used for any "Positive" ( + ) Voltage
Black - this is generally used to represent "Negative" (Gnd) -
For Signal wires they can generally be any other color, so blue is fine. However if you are using multiple signals, make sure to pick a different color for each signal. Remember only use "Red" & "Black" color for power

This is a very big yes, thank you. And yeah wasn't sure which colours i was choosing cos I'm partially colour-blind 😅 red and black close to each other blend for me, and red and green is just a nightmare, so blue helps 😅😅

Hope this helps
I rewired (and recoloured using someone who can see) but my power supply still has different readings than your ones with 0amps coming from the power supply connected to the arduino?

Is your code loaded into the simulator ? If the code is not loaded or incorrect the Arduino will not process , and no power will be used.

I think so? I used a generator and it says that it uses the neopixel library. I then copied the code into Tinkercad. It's definitely works since it's running and lighting up, but the only difference I see is the power balance?

The power draw will be very different. The Neo-Pixels will use a lot more power than the Arduino. Since the Arduino is not provding the "power" to the Neo-pixels only the signalling, it's power consumption will be very low. In reality the Aruduino in this setup is most likely using less than .02A

Do you think it'll be OK to wire up as it is then? Also where would I put a switch do you think an alisha board would be a good addition?
sullen mortar
The wiring should be fine. If you are going to use a switch, there are many possibilities depending on what you want the switch to do and what type of switch do you plan on using.

I'll be happy with it just turning on 🤣🤣
