There are lots of DIY led Music Spectrum kits available in the market, but here you can make your own led Audio Spectrum Analyzer using NeoPixel rgb led Matrix and ARM microcontroller. led Audio Spectrum Analyzer Circuit: How to make a led Audio Spe
Are you speaking of a rgb led?
Hi I want to find a way, to controll rgb led color (specific color for example 5 or ten specified color) with a tact switch and without micro-controller. on the other hand want to use simple and cheap material. thanks for your help
Hello I'm making kind of a project right now. But, i've got a problem with choosing a power supply. I need three times 7.5A continuous current. Will I be able to use a 650W PC Power Supply for this project or do I have to buy a different one? Here's a link to my power supply: .
Hello all, I am trying to control the brightness on 8 separate common anode rgb led strips(24 Channels) of varying lengths using a single Arduino nano or Mega board. I have found other threads and online articles suggesting that a TLC5940 chip(16 channels) with the help of MOSFETs can do exactly that. However I am merely a student and have b
Sounds complicated and if you intend to run one I2C bus around them all you will run out of addresses, bus drive capacity and speed. What are the IR phototransistors detecting? Most need a fairly 'bright' IR source before they give significant changes in their current and that current has to be detected somehow. Cheap rgb leds can be just as goo
I am using NCP5623 led driver for the rgb led.. The code isn't working in hardware. #include #include #include #pragma config PLLDIV = 5 #pragma config CPUDIV = OSC1_PLL2 #pragma config USBDIV = 2 #pragma config FOSC = HS #pragma config FCMEN = ON #pragma config IESO = OFF #pragma config PWRT = ON
Why wouldn't someone want to? If there is a spice model for a single led, why would rgb led be an exception. Sorry if that's hash.

I do not know for rgb model, but for single color 16 x 32 dot chinese led modul there is 16 pcs of 74hc595 (1/4 refresh). Each panel have 74hc245 buffer on data, clk, latch and enable line. There is one NOT gate, i think on enable line, hc138 decoder and 8 pcs dual p-channel fet transistors in SOP8 package for driving rows
Hi guys, recently I got an Philips LivingColors lamp. I wasn?t too happy with its brightness so I decided to do small hardware modification. I added few N-channel transistors to the led drivers and connected an rgb led strip. The effect was really impressive. The single lamp with a strip was able to light up the complete room. The control (...)
Hi, I'm looking for a Looking for very cheap rgb led in SMT package, low power. Thanks, Enrico Migliore
Hi guys, Im interested in building an led controlled by an app on my mobile. Im wondering what components would be required in order for this to work. So basically a small battery would be connected to a Bluetooth chip with an rgb on the other side. If anyone has any circuit diagrams that would be great help.
Hello, I am trying to drive an 8x8 rgb Common Cathode led matrix. I am planning to use four 74HC595 shift registers. The problem is that I want to get the maximum brightness out of the leds but I do not know which IC to use between output of shift registers and leds. I am using 5050 smd rgb (...)
In simple words, you need to adjust the individual led currents to get same luminuous intensity (according to eye sensitivity curve). led datasheets are usually showing the eye corrected intensity (luminuous intensity in cd), so you can calculate a rough current ratio. But rgb leds have also intensity variations between (...)
What size are you looking for? There are 1"-2" single digit rgb displays out there, but nothing smaller as of right now.
Hi ppl, I'm new here and I didn't see an introduction page, so I'll introduce myself here :). I'm bart and I'm new to electronics. I want to experiment with led lighting in my house. I've got some questions and I hope there are some people out here who could help me out. I have the common 5m led strip 5050 rgb (300 led (...)
i want to fetch rgb led matrix frames from SPI RAM and scan it @ 60hz. i have decided that one controller fetch data from SPI RAM and share it to other controllers through its USB port they will do scanning and PWM stuff. this will save complex h/w like dual port ram etc. any suggestion regrading this ???
It seems that here the 4-pin rgb led has a common anode (connected to +), right? On the other hand, if the board could be supplied by different 12V sources and 11V is good for the board, placing a forward diode in series with each source and joining the diodes at the other side, the board will be supplied automatically by the highest voltage ava
