I’m currently trying to make a basic domotica system.
I need one central box which “warns” me when something happens. As I’m deaf, I can’t use sound signals to indicate this, thus I need a visual signal.
The box will not always be in line of sight, but even when I’m not directly looking at it, it should be clear when an event happens.
I am trying to find the cheapest way to solve this poblem. The flash should be very bright, as it should always be clearly visible, even when the sunshine floods my living room. I wouldn’t mind using colored leds, as those might maybe more noticeable, however I have no idea whether or not colored leds would be cheaper / as bright(/noticeable) as white leds.
It should be able to run off 5v or 12v.
I would like the total price of the LEDs + resistors to be under 4$. I am not going to use a constant current driver as those make things more expensive, and the leds are going to be flashed very briefly and will be used indoors, so the temperature shouldn’t be too much of an issue.
Sorry for not being very specific, but I am open to all suggestions and ideas, maybe even something I haven’t thought of yet.
Can anyone help? <3
