LED Full Spectrum Controller based on Mega2560 board - Page 2

KDHL · 01/22/2014, 01:41 PM

kapelan,

Very nice... where can I buy one instead of building one myself?

bigguyuk · 01/22/2014, 03:33 PM

I have a Question please dude
If you wanted to run say a small sting of blues for moon light is this possible
As when you Buy Led drivers you get 350 700 and 1000
can the drivers be changed to suite this or do you have to but the LEDs to match the drive
Hope this makes sense been looking at doing LEDs For 18 months now and still do not fully 100% understand it all. But Love the challenge and i do like the design of yours

Is the code easy to play with.
Thanks again
Simon

kapelan · 01/23/2014, 12:20 AM

Led drivers can be adjusted.
1000mA is maximum

bigguyuk · 01/23/2014, 12:01 PM

That's Great News

bigguyuk · 02/08/2014, 04:17 PM

any updates on this

The TLC5940 is what I'm thinking of. AdaFruit sells a board for it.

If you are thinking of getting the TLC5940 ... don't. The better board to go with is the PCA9685. It's I2C so it won't interupt your cycles on the cpu. It has it's own timer.

Version 2.02.
Main board includes:
- timer chip
- PH, ORP channels
- 8 channels power block (relay)

On the right side the bower block, triacs and connector which goes to power sockets:

Drivers PCB, 8 drivers on the board each up to 1000mA:

is there available sketch?

kapelan · 06/10/2014, 01:07 PM

v2.02 software:
https://docs.google.com/file/d/0B42Z...84b2UzYkE/edit
Now each timer has seconds.
Each channel controlled by 16 timers.

bigguyuk · 06/10/2014, 03:05 PM

Nice one dude

Alx1280 · 06/10/2014, 03:38 PM

Congratulations. Very well done. Super clean solution. Would it be possible for you to update the BOM and support to get boards fabricated to replicate your controller? I am really expectant for it.

kapelan · 08/18/2014, 09:32 PM

Update.
-------------
Shortly about this device:
- 8 fully controlled LED dimmable channels: sun/sunset/clouds/lightning storm modes.
- Controlled 8 power lines
- For each power line 16 timers
- Each timer with second's precision
- Support 4 overflow sensors
- Temperature control
- PH control
- ORP control

From the back pannel:
HDMI connector - for LED drivers
USB 3.0 connector - for temperature sensor and overflow sensors
BNC - one for PH another for ORP probe

From video the system in a cloud mode, i.e. each channel slowly fading, it looks pretty cool: controller changes color randomly (I love this function).

Hi Kapelan i really like your controller where i can find the wiring/operating instructions, i.e pin outs for led channels etc. I was also wondering if it can be adapted to be used with meanwell LDD drivers as i have these already.
I was going to use the Stilo 3.0 but after months of frustration with coding /compiling errors (newby to Arduino) i got the code to compile but my display keeps refreshing every 2 seconds and i can,t solve it despite following posts with the same problems i finally gave up on it.
Your upload worked straight away and is displaying on my screen, but i cant find the operation/wiring instructions.
Thank you.

dlarmond · 11/27/2014, 10:10 AM

Can anyone help me on this , as this thread seems to be dead.
I do not seem to be able to find documentation on this controller i.e. what each pin of the arduino controls what function led channel etc. , is it available. .Newby help !!!!.

kapelan · 11/27/2014, 08:34 PM

One wire bus for temperature sensor DS1820: A3
Timer DS1307 rtc( 42,43)
LED pins: 13,12,11,10,9,8,44,45
Cooler for LED: 46
PH: A1
ORP: A0
Power lines: A8,A9,A10,A11,A12,A13,A14,A15
To contact sensors (overflow): A4,A5,A6,A7

dlarmond · 11/28/2014, 11:09 AM

Hi Kapelan

Thank you very much for that information , i am going to have me some fun.
Cheers.

kapelan · 12/04/2014, 07:44 AM

That's kind of innovation.
LED levels are configured as a chart now: just point the desired level on the screen.
The system will create a chart and all related timers.

nice and easy

kapelan · 12/09/2014, 09:32 AM

I'm thinking about a new design:
Create a PCB: all in one.
I.e. we actualy do not need a shield between Arduino and TFT screen.
So it would make sense to create a new arduino to which TFT attached directly.
I mean it would be the same chip, all compatible to Mega2560, that should work with touch screen without any other PCB.
So assembled device will have only 2 parts:
- a new PCB, which is equivalent to Arduino+TFT shield
- touch screen.
Anybody would be interesting?

Hi Kapelan is the new led level screen that you posted 44 available in version 4 of your code , or do I have to download another updated version.

From this link it's the latest version.

Here's one I've been working on. Went a little different route. Instead of going Atmega 2560 I went with the 1284P. Less flash, but more RAM (16MB) and EEPROM (4 MB). Good trade off I thought since it allows more flexibility to work with data at run time.

This is only 2.7" x 4", has 6 PWM ports, 2 x 16 AMP SSR controlled AC outputs, a DS3231 RTC, 2 ports for float switches and on board 115 AC to 5V DC conversion. 1 AC plug (no wall warts) drives it all. This can control anything from LED strings to metal halide lights, dosers, pumps, etc.

Working on a version that has 24 pin sockets for Meanwell LDD drivers on board. That one will be controlled off a DC power supply similar to what you've done. All one board though.

v.2.05 update: https://drive.google.com/folderview?...kU&usp=sharing
1. Added Chiller. One sensor can control chiller and heater.
From touch screen we configure Area of Comfort.
If the temperature greater then Alarm Level – chiller turn ON. If less than some level - turn on the heater.
2. Added support for up to 4 temperature sensors.
