Thanks Duane, you can find the code as well as the Eagle files here: https://github.com/jersagfast/RGBW-31
The code is pretty well documented, but let me know if you have any questions, thanks.

Hey Jeremy, i was messing around with some programming on the unused IO pins and i accidentally loaded an old firmware on one of my kits. I cannot seem to load the 3.1 firmware on from your github. i get an error compiling that says "Adafruit_NECremote" does not name a type and line 53 is highlighted. I have the remote files in a libraries folder in the sketch folder. Not sure what i'm doing wrong. It seems to work fine with 1.9firmware loaded on.

Other than that one i messed up, they are working great! They have been a fun project to built and mess around with. As soon as it warms up here in Canada, im going to run a strip of RGB lights around my house behind the fascia. Its going to look pretty sweet!

Also i would like to try and implement this colorfade sequence explained here....

http://www.freestylersupport.c.....w_tutorial

It seems to provide a smoother transition between each shade of color. It looks less "bouncy" between colors.

I've tested the sequence out with a dmx RGB dimmer i have and it works REALLY well.

Thanks again soo much for sharing this project with us all.

Hi,
How much output power can we get from this controller (using the matching power supply of course). I have 12 x 72W 5M RGB led strips, how many controllers should I buy if I want to control all the strips at the same time (same color, same everything)
If I want to control them independently, is the controller addressable on the rs232 side? Can we give address 1 to 12 for as an example 12 controllers and send control commands to only one of the group even if they are all connected to the same rs232 port?
Thanks!

Hello everyone,
I have a questions
1.what RGBW LED Controller ver 3.1 rs323 Communication Parameters ?
2.what script format you specified in the instructions ?
red(x)
green(x)
Or this ASCII text format ?
Thank you very much

Hello,

I have tried to open the schema and board files with EAGLE but it says it can't open the file because there is an error.

Is-it possible to fix that ?

Hi,
RGBW controller requires three different addressesFrown

Hi Jeremy,
I have successfully built the RGBW Controller - I'm very impressed with the quality of the kit and the instructions (I'm in the UK - I received the kit within 2 weeks of my order - thanks!).
I have a few comments about the Arduino sketch and the hardware:
1. I found that the serial commands for colours (sorry, colors!) were returning invalid values - the sketch was picking up digits in the wrong order. I made some changes in serialchk() - e.g., for red:
digit1[1] = datain[5];
digit2[1] = datain[4];
digit3[1] = datain[3];
Similarly for other colours.
I found that you have to give commands such as red45, whereas the manual suggests red(45).
2. You cannot reduce cycle rate using the remote (vol -): hearir() never passes remval = 0 to remoteck(), because oldc is initialised to 0, and so oldc != c fails when c=0. Also, c=oldc (3 lines down) means that oldc never changes. I made the following changes:
int oldc = -1; // (before void setup() )
void hearir() { // listen to IR sensor
int c = remote.listen(1);
remval = c;
if (c != oldc && c>=0) {
remoteck();
}
oldc = c;
}
3. I found that the resistors for the RGB and white LEDs were too low - in particular, R1 at 82 ohms meant that blue swamped the other colours at anything above a few %. After some experimenting with a separate RGB LED, I changed R1, R2 and R4 to 1k, and R3 to 470 ohms - these values seem to work OK. (Incidentally, the manual shows the colour code for R1 as 820 ohms, whereas it's supplied as 82 ohms).

I hope all these comments help - the board is currently doing a great job driving my LED strips!

Hi Jeremy,
Just recently purchased controller ver 3.1. Price is great. Assembly instructions great. Up and running no problems with the FTDI and 5 volts USB and the jumper set on 12V. Here is what I'm seeing though. When I plugged in with a 12 volt aux power unit, the blue power light comes on, but the controller does some unusual flashes on the 2 LED lights, then continues with random LED flashes (usually red) with several seconds between flashes. I have a left over LED strip (RGB 5050 requiring 12 V) that is approximately 4 foot long, so I attached that. And again, with the 12 volt external power supply, it doesn't run properly. HOWEVER. I happened to plug in a 9 volt external power supply, and now everything is running fine. It's been up and running as advertised for several days now. So I checked the actual volts of the 2 power supplies with my Digital Multimeter. The 12 volt unit shows 12.15 volts. The 9 volt unit shows 9.42 volts. I'm a little surprised the 5050 LED strip is working at 9 volts. Probably because it's only 4 feet long.

What are your thoughts on why the controller will run with the FTDI, and 9 volts external, but not 12 volts external? Thanks. Greg

Hi Greg, I would suspect a "dirty" power supply. I would check the power supply with an oscilloscope or if you don't have one, add a capacitor to the voltage supply. I have seen caps as small as 470µF clean up dirty power supplies. Hooking up a 25V 470µF (or higher) cap in parallel might solve your problem. Let me know if this helps. 🙂

Hi

I'm investigating DIY LED controllers and these seem to be the best design I've come across but they are missing one feature I would like to have which is DMX, how hard would it be do mod this to add in a DMX receiver, i.e. with an RS-485 transceiver and a bit of code to do the rest.
It would be nice as I use DMX stuff all the time in one of my Jobs and this would allow me to build my own LED fixtures.  

Did you ever get an answer form then CustomGeek on DMX?
