I am about to start an arduino project with smd2835 neon lights and a 12v power supply. They don’t use DuPont cables. I just wanted to know how to connect the wires to the breadboard without DuPont. I’m fairly new to arduino too.
Welcome to the forum
Please post links to the devices that you are using ?
It’s just an arduino uno, a standard 12v power supply, logic level n channel mosfets etc. a generic breadboard too. The lighting is a neon 12v strip
Here’s the link for the light

Here’s the link for the power supply

It’s fine if the wattage etc doesn’t match up it’s just a rough idea
The obvious solution is to solder wires to the light strip as suggested on the page that you linked to
I thought so thanks. Another question - do I just slot the wire to the hole in the breadboard? I don’t know if you need DuPont for a breadboard. I’ve never used one before so I just wanted to make sure
You just need a firm point to the wire. If you are using stranded wire you can use a ferrule or if singe core it won’t need it
One may consider the power requirements of the led strip and the ability of a breadboard to supply the necessary current for the led strip. A breadboard does not allow much current flow, tiny wires.
So as long as it is in the breadboard it should work?
Is there a workaround?
You don't need Dupont connectors to use a breadboard but if you use stranded wires it is a good idea to twist the strands together and tin them. Your best bet would probably be to cut the end off a Dupont terminated jumper and use that for connection between the breadboard and the light strip
From the nature of your questions it seems that you do not have much experience with electronics. Please post a schematic of your proposed circuit. A picture of a hand drawn circuit is good enough
I make my own circuit boards.

It draws 3 amps according to the description. I would not like that on a breadboard
I don’t currently have one it’s a work-in-progress idea. I’ll post one in the coming days once I’ve figured more out. Thanks for all the help though I really appreciate it
You can just solder the wire direct to the mosfet pins. Or use a small strip for testing.
I can do that. A bit more research and hopefully I’ll be ready
Do you think I should use a PCB instead of a breadboard?
I will be cutting it down to about 1.5m so the ampage would be around 1.2. Would that be alright for a breadboard?
It might be ok for testing for short periods. But do not leave it running unattended and monitor the breadboard and components. If they get hot, immediately disconnect the power.

A breadboard is only for planning out a circuit and I don’t think there is a standard so unless yours comes with a rating I suspect it will only be good for 1 or 2A at the most and should not be left unattended or running for long. Once you have things working make a more permanent solution
For a permanent solution should I use a pcb? If so do I find a generic one or do I get it made
