Aquarium LED driver? Answered
im looking for a schematic that controls 1w leds for my fish tank light? i need the control to be dimmable and hopefully programmable so i can incorporate a sun motion effect and then a moon motion effect! i say hopefully because this will need to be an add on later in the project as id like to have the initial lighting up as quickly as possible! As far as i know so far, the circuit is a basic constant current circuit but i need a "buck" driver or PWM to enable the dimming by varying the current! so my questions are :-
1. Does anyone know of a simple, reliable and cheap circuit to use?
2. Because of the amount of LED's ill be using im not sure i like the idea of having all the lights in a series configuration because if one fails, thats a lot of lights to test!
3. If i have to use a computer to run the lights id like to be able to make it compatable with the raspberry pi therefore id need a program and mounting software for the pi, so anyone know of one?
4.Right to the power, i dont care what voltage it runs on but id like to only utalize one plug socket if possible, i do have a few power supplies laying about for various things like old laptops and old pc's, so what do i need to power it!
i cant think of any more at the moment but you guys know what im trying to achieve so im sure you know what questions i have missed! as i said though, id like to start simple and work up to sun motion control and timers!
Thanks in advance for any help anyone is offering!
