LED Board project
I have been tasked with trying to build some sort of led lighting system, using leds in series.
As soldering LEDs is more challenging, and I lack the proper kit to wire everything together properly. I have built a basic prototype below.
However this is drawn on a previous project, which does work, this lights up 4 or 5 white LEDs.
i am now working on version 2 (below) of the board, so need to find a way to solder the LEDs to the board, so they all light up nicely, don't draw too much current and can be daisy chained together.
This is not that easy, as i am NOT an electronics expert, I have some expertise, but don't always know exactly how to do things like this, so it is more a case of experimentation.
I have two versions being developed in parallel to see what works, one problem is the LEDs all have different current requirements, depending on the colour.
The main issue is powering this project, I was asked about USB, if you do this from a PC, then you get 5v @ 300mA (I think) which is not quite enough, if you power from a USB charger than you are connecting to mains.
In both the above cases there are serious risk issues as if there is a short, it may not just cut out. I am not risking it.
If we power using a battery then this will deplete over time, and in the case of a short circuit, will overheat.
I may try and see if I can use a breadboard power unit, as this does offer some degree of protection from short circuits.
