Who wants a cheap, simple, Arduino-based LED controller?

Just to confirm, the hour and minutes remain constant at 0. It will neither let me increase or decrease them. The +/- does work for other menu functions.

The Typhoon does Pulse Width Modulation so the P version is better suited.

Thanks!

Wanted to make sure before I order drivers (already built the controller)

On a side note, is there a hope for moonlights/temp sensor/fan control add-on to happen :) I'd love to toss the stock analog timer that runs moonlights and fans and replace it with Typhoon ( there is a perfect spot for it in the red sea max hood)
 
I may have missed this somewhere in the thread, but can this controller be done with a simple arduino board, lcd, and rtc chip?
 
No to control the MW you have to convert the 5 volt PWM signal to a 10 volt PWM signal. It is a fairly simple transistor circuit. If you read the Typhoon thread you will see a schematic there.
 
I know that there was some talk further back about there possibly being a way to link two typhons, has that been explored at all yet or still in the process of finishing the original?

I myself would be very interested in that aspect as i would like more pwm channels of control.
 
Is it possible to use the boards power supply to drive one or two small leds for a moonlight? I am thinking one or two 1 watt LEDs @ ~350mA or less. I plan to use a 12v 1000mA power supply, so I figure there should be plenty of "extra" power. It would be nice to not need another power source for them. Also is there any reason that both 5v and 10v pwm can't be used? I'm planning to use Mean Wells for the main LED arrays, but may use a Buckpuck for the moonlight.
 
I have not heard of linking typhoons. But you could just manually keep the clocks syncronized. Or have the master send out a pulse a midnight to to reset the slaves.


The 5V and 10 V are tie together. There are 4 signal from the Arduino that are then converted. You can use both but you only have 4 controls.

The voltage regulators may get too warm/hot. Otherwise it should work. Or are you hooking the BP u pto the 12 volt directly - then is should be OK.
 
I got a board from futurelec that has 4 relays on it. I still haven't started working on it, but others have used it with the Arduino. Remember th typhoon has 4 PWM. White, blue, moon light and I thnk someone has a fan running on one..
 
Do anyone know what happened to my PCBs?
I used the zip file found on seedstudio to create the gerber files.
I sent the same files to iteadstudio and I recieved 10 cards looking like this:

Some of the silk is missing, but I guess this could be something with the gerber files. No big deal.
What I can't understand is how the three holes in the upper left corner (behind the pot) got there.
Where did these come from? They are not present when I am viewing the file in Eagle.
Is there something I have missed?

I have not found anything wrong with the rest of the board so far.

Torhav,

Looks like you found my modified version of the board. I dunno what is up with the silkscreen, but The 3 extra holes are for a fan input. No code for it yet, but I'm working on it. The only thing it will require is a small board w/ a separate 12V regulator and transistor to act as switch. I'll send you the design once I finish prototyping it.

I really don't know where you found it, but I am the only one I know that has that extra modification. Good to know it still works though. :)
 
Maybe there was something wrong with my gerber files and they figured it was the same project and used your design?
This modification is not present on my eagle files.
I have done a little research, and found the pin on the arduino chip to be a PWM output. Is this correct?
Is it also correct that this is a 10v signal, output #2 from the bottom?

You can control many drivers from a single PWM pin on an Arduino, but of course they'll be controlled together - if you have 8 drivers and you want to control all 8 independently, you'll need a Mega, or a Mega clone, as the ATMega1280 it's based on has 14 channels of PWM.

can I use a non inverting buffer to feed the PWM from arduino to the cat4101?
Thanks.
