I bought a 20x4 screen off ebay there are tons they dont make a shield for this screen you have to also order a pin header for it as it does not cone with one usually
(Another) DIY LED Controller - Simple Arduino Style
- Thread starter katchupoy
- Start date
i am using 16x2 But I cant upload anything ! I tried to up load hello world It said it was uploading to board but the display is blank! Please Help!

JeffD did you buy the lcd shield? did you put it on top of the arduino? then you have to change the code because we rewired ours (remote connection) to free up some pins....
You have to show us pics of your gig...
See these lines.....
If right now its on top of your arduino as in directly plugin... then use the typical set.... 8, 9, 4, 5, 6, 7

katchupoy, How can I add a few small blue LED's powered by the arduino as moon lighting for a few hours to the code and board?

katchupoy, Ok so looking into this a little more I need you to add a moonlight phase to my current sketch if you wouldnt mind. I want to add 6 or so blue small LED's to my project on whatever pin for a moonlight phase from 8am to 10am and again at 10pm to 12am. Hooking up the LED's I will use one of the transistors and supply power just like its setup for the meanwells.

This controls the dimming on the meanwell driver from off 0% to full blast 100% and in between. The meanwell plugs in to the wall outlet and this controls the on off dimming cycle so in a sense replaces the timers and you can use them on something else now

after 3-4 hours of screwing around and trying to find the "right" BMP to hex converter....I finally got custome images on the LED. There are 3 images: sunrise(fade in), sun up (max), sunset(fade out). Each will be shown during appropriate cycle. Making a moon image as well.
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

Ugh. Long post eaten...
Short version. Got pretty comfortable doing static images on the GLCD (graphical). Not sure if it will work on the 16x2s, etc. I'll put together a post on how I did what I did later.
Going to start working on the IR interface. Wondering about making interactive menu via LCD and buttons. Not idea where to begin on that one.
Spent too many hours trying to get % ramp up/down per minute, but gave up in frustration and pain of a new head cold. 10% steps will have to be good enough for now.
thanks again for the work you guys have done before me. I doubt I would have tried if I would have started from scratch on my own.
The times on the right are temporary and stand for blue up, white up, full on, white down, blue down, full off.

You called relay 1,2 but actually just a switch for transistor to enable the meanwell?
Eventually, I can put a solid state relay here to turn on my power supply on/off instead, correct?
int bluepercent[11], does this suppose to be [3]?

shikhyung, no that is for a wavemaker setup but I see no reason why you couldnt modify the code to turn on and off the power supply

I am currently trying to add a 3rd led control for moonlighting so far no dice wish me lick lol I messed something up
