RGBW LED strip current

Hi,

I have a stupid question and since it's referenced in the "MySensor shop" I would like to post here

The LED strip on the "MySensor store" here http://rover.ebay.com/rover/1/711-53200-19255-0/1?icep_ff3=2&pub=5575069610&toolid=10001&campid=5337433187&customid=&icep_item=171158397695&ipn=psmain&icep_vectorid=229466&kwid=902099&mtid=824&kw=lg
says

Specifications:
● Color: RGBW Mixed
● View angle:120°
● Working Voltage: 24V DC
● LED Quantity: 300 leds/5 M(150pcs RGB LED and 150pcs White LED)
● Working Current/Meter: 6A
● Output power: 72W /5 Meter

As I understand 5050 SMD LED have a standard power consumption of 0,24W/LED = 72W for the one above which seems ok. With 24V it should be 3 Amp for 5 m (72W/24V) and not 6A per meter as it says.

Also it would be good to have a good recommendation on 12V LED driver as you also have 12V LED strips in the shop

@Nca78 Yes, I was actually thinking using DIP switch (or even more easy to read thumbwheel switch) to give a unique ID to each node! As soon as I receive the extra radio modules I ordered, I'll test that. @Grubstake I'm afraid you're right! But it's ok to have just a few days of battery life. As I wrote, it might be often disassembled and reassembled.

@yoshida I'm not sure... Maybe

@mfalkvidd said: I am using them at 12V so the power would be ~4W. Not too much but still enough to get the sink hot! The voltage makes no difference. 5A is still 5A. you are right brain fart

Good point! Will consider in the next version...

@Samuel235 said: Just one of many ideas, the possibilties are endless. I'de always go for RGB leds over just white, allows for more customisation while able to still give you the same white as the white leds. ... unless, as in my use case, colors are not needed. I'm too stingy to pay for the unused dry powder!

Thanks for the reply. I am not looking to use an LCD, although that may be the best solution. For now, I plan on creating a simple set of LEDs and buttons. I have looked over the code, and was wondering which part of the code is retrieving the status of a sensor? What if I have multiple motion sensors, how would I retrieve each unique value?

@krisztian Hi krisztian, the singleLED board - as its name suggests - features only one LED output. If you want to have a setup with multiple LED strips you need to design a board with multiple outputs. I have already designed a board with 4 outputs, but I haven't built it. In terms of software you need to register multiple sensors in your program like this: #define numCh 4 //the number of outputs const byte ledPins[] = {9,6,5,3}; byte ledLevel[numCh]; boolean ledDimWay[numCh]; //in the setup function request the dim levels from the gateway for(byte i=0; i<numCh; i++) request(i, V_DIMMER); //in the presentation function register multiple lights for(byte i=0; i<numCh; i++) present(i, S_DIMMER); //if you receive a signal, you need to check for the sensor id setLED(message.sensor, requestedLevel); //to set the LED level (function: setLED) you need to use the sensor id to determine brightness and pin //Fade LED to set level int delta = (level - ledLevel[child]) < 0 ? -1 : 1; //Write to LED analogWrite(ledPins[child], map(ledLevel[child],0,100,0,255)); I will probably publish the whole code once I have built and tested the 4LED controller (i call it "MySensors rainbowLED") Hope I could help you ThetaDev
