(Another) DIY LED Controller - Simple Arduino Style

Near the top is the zip with the library.
http://www.arcfn.com/2009/08/multi-protocol-infrared-remote-library.html

Don't think it's related. I'm suspecting it might be a memory thing, but I just don't know.


Trying stuff...heh


EDIT: Seems I was right, maybe. I trimmed some code by making sub routines and now the flicker/artifacts are mostly gone. The screen is still a bit 'off' but only the time changes every second. Going to do some more 'weeding' and see if that clears thigns up.

EDIT2: Nope, not fixed. Seems that my "night time" layout is causing some of the issues as it is much better once the light cycle starts...

EDIT the 3rd: And I now have a fan running off one of the PWMs, so I'll take that as it works...hehe.

EDIT 4: Commented out the IR code and now the screen is more or less normal...wish I knew how to code better...

I'm a little embarrassed as it's pretty ugly in places. But here it is. The fan was a simple analogWrite(fan, 255); where fan is the pin and 0 and 255 were used for off and on. Actually only pushing 5v to a 12v fan for testing but it works.

pastie link ***ed the first part so here it is in 'php':

EDIT: I also got a little excited as I found a box, in the basement, for an external CD/DVD with a 5v and 12v lead/power supply. The screen doesn't quite fit so I still have some figuring, but other than that it's sweet:

also I would not power the fan from the arduino instead hook it up just like we do the meanwells with a transistor inbetween the negative of a power supply and the fan..... I am ordering a 10v regulator and a 7.5v regulator if I can find one and I will build a small power circuit to power everything off a regulated 12v radioshack wallwart. Arduino will get the 7.5v regulator and the meanwells will get the 10v regulator anything else like nighttime LED's and fan will be fed the 12v straight with no regulators
 
Hmmmm try to get that fan working from a analog pin would save us a digital input. as soon as my girl leaves for work I will get my fans working on this or at least try

Running the mega 1280 with 50 digitals, not worried about saving one. :lmao:

As well I'm planning on setting up mine like ktnch: http://www.reefcentral.com/forums/showpost.php?p=18566367&postcount=302

I'll have 2 extra regulated 10v PWM signals (running through a 2nd op amp) so I figured why not use it.

At the moment I'm turned off by the IR as it was mostly gimmick. At this point I think I'm going to move on to buttons and some sort of menu...pretty scared...heh:confused:
 
So I still have the occasional artifact...any thoughts? Basically it's like it refreshes the screen but maybe one letter is shifted partially.

I have another question of "correct" coding. Let's say that I print the word "Start" and an hour later I print the word "End" in the same place. It ends up looking like "Endrt" because the last 2 letters are left over. Is there a smart way to get rid of the previous word? Currently I just do something like "End " adding spaces to clear out previous text...
 
yup just add a few spaces to clean it.... as for the artifact issue no idea other than its in the code somewhere..

Hello!

I´m making this build and it is "kind" of working, I say "kind" because the leds dim are made with huge steps, not smooth. In the first step, 0/1 to 26 it ligth up like 0 to 40% or 50% of total power. When it turns on I can see leds with a very wheak ligth, on the next step... BUmmm, 40% of total power. Same thing on both blues and whites.
I´m using the 48P driven with 2n2222.
As I´m in test mode I have my ramp´s set to 10 minutes now.
Already tryed to change this :

int bluepercent[11] = { 0, 26, 52, 78, 103, 128, 154, 180, 205, 230, 255 }; // this line is needed if you are using meanwell ELN60-48P
int whitepercent[11] = { 0, 26, 52, 78, 103, 128, 154, 180, 205, 230, 255 }; // these are the values in 10% increments

to lower values like : 0, 2, 5, 10, .... no luck.

So, is this behaviour normal or do I have something wrong in my code?

many thanks,
Henrique

First of all, welcome to RC, and to my thread.... I apologize for the delay, im done moving but everything right now are scattered everywhere and still in boxes... its very chaotic....


this is not normal.... please double check everthing specially the wiring... are you sure, you are using NPN? because you can easily have it mixed with PNP? do you have what i have? as in terms of hardware? what kind of hardware do you have, please list it here.... do you have a pic?

Im curious as to why it acts like that...

You should have something like this....

PHP: 
//int bluepercent[11] = { 0, 1, 2, 5, 8 ,12, 18, 27, 44, 80, 255 };   // this line is needed if you are using meanwell ELN60-48D
//int whitepercent[11] = { 0, 1, 2, 5, 8 ,12, 18, 27, 44, 80, 255 };   // these are the values in 10% increments

int bluepercent[11] = { 0, 26, 52, 78, 103, 128, 154, 180, 205, 230, 255 };   // this line is needed if you are using meanwell ELN60-48P
int whitepercent[11] = { 0, 26, 52, 78, 103, 128, 154, 180, 205, 230, 255 };   // these are the values in 10% increments

To all, there are 2 functions on this sketch...

FUNCTION 1
We are only talking about "one" function... which is the ramp down and up of two channel/s. One for white and one for blue...

FUNCTION 2
We just need (FUTURE) to add a low voltage relay and this can be used as a wavetimer. We have two channel/s already built in on this sketch. This is "RELAY1" and "RELAY2". Arduino PIN 2 & 8

Hello!

I´ve tried the 2N2222, pwm out to transistor base , with and without resistor, and also tried the ICL7667 with same results (only diference from transt to IC was 255=0 and 0=255)
To have something similar to a fade I changed the ramp code to:

int bluepercent[11] = { 0, 24, 25, 26, 30 ,50, 70, 100, 150, 200, 255 }; // this line is needed if you are using meanwell ELN60-48P
int whitepercent[11] = { 0, 24, 25, 26, 30 ,50, 70, 100, 150, 200, 255 }; // these are the values in 10% increments

My hardware is a Mega, HD47780 20x4 display, ds1307 RTC, LM35 for temperature.
The 10V for dimming came from wall power supply regulated by a 7810 but also tried with a 9.5V PS with same results.
Is it possible I have the wrong transistor?
One thing I note is that when fading out is more sustainable, a bit more smooth.

Thanks for your help.

Any one had any luck with buttons? I was able to run a simple sketch and it worked just fine:
PHP: 
#include <Button.h>

//create a Button object at pin 12
/*
|| Wiring:
|| GND -----/ ------ pin 12
*/
Button button = Button(12,PULLUP);

void setup(){
  pinMode(13,OUTPUT); //debug to led 13
}
void loop(){
  if(button.isPressed()){
	digitalWrite(13,HIGH);
  }else{
	digitalWrite(13,LOW);
  }
}

But when I added the pieces to my main sketch it didn't respond at all. I spent about an hour+ trying different pins and commands with no luck. Any thoughts?
