I have recently started to learn about electronics and as my first project, I'm trying to make a wifi-enabled LED strip.
I have read a lot about all the theory, followed tutorials, and try to be extra careful because well, toying with electrical stuff can be dangerous.
I don't know what to use to make electrical schematics but I took photos of my design and I would feel a lot safer having some feedback from experienced electrical engineers, especially about my chosen wire size (details below).
Here is some information:
- Power supply: 5V, 3 amps (max).
- LEDs: WS2812B (20 leds separated in 5 groups of 4, each connected through).
- Controller: NodeMCU
- 26 AWG silicon wires for connecting the LED strips together and also the power supply to the first LED strip.
Here is an overview of the thing:
And here is a close-up of the board, top and bottom (my soldering skills still need improvement, there is no doubt):
Now my main concern here is:
Is my chosen wire size (26 AWG) adequate for such sustained full LED brightness activity?
From my calculations, LED at full brightness (full white) should draw a maximum of 60 mA each, so 1200 mA for my 20 LEDs. I've let that design run at full brightness for an hour now, trying to see if things get hot and so far, it doesn't seem to be the case. But that's hardly a guarantee, especially as I plan to put the PC in a plastic casing in the future, so I assume heat will dissipate even less.
