If there is something on the strip it has to be a resistor. I am supposed to be getting a sample in the mail some time soon.
Does anyone have a good resource where I can read up and really get a good grasp on transistors, (types, selection, etc.)?
What I have right now is this:
My...
I apologize, one of the downsides of typed communications unfortunately. I'll look into heat sinks. Once I think I've found the right transistor I will post it up!
I agree that the spec sheet isn't very informative. I believe that the LEDs are parallel in groups of three on the strip (which...
You trust correctly, phinds asked the logical first question. Thank you for the links, the first one looks particularly helpful. I'm going to spend some time going through it.
This is a link to the data sheet for the LEDs...
That is the typical first response! Ideally I want to be able to control about 1,000 LEDs. This control unit will be used for automotive applications and so the LEDs being used (having also been set up for automotive use) are run at 12V.
I'm building a digital device for controlling LEDs. I need some help figuring out the correct transistor for switching use. The control circuit will run on 5V (and that will be the voltage applied at the transistor base when current is to flow through) and the transistor will have to be able...
I basically need to control four distinct groups of LEDs. I'm including a link to the spec sheet for the LEDs I'm using. I'd like to control between 600 and 900 LEDs. I honestly don't know anything about PWM current sink circuits so I will begin researching...
Basically what I'm making is a controller for LED's (in an automotive application) and it has to be able to power a lot of them! I selected tri-state buffers as a way to connect multiple inputs to the same output and select which input is used based on input to the device. I'm really not sure...
Hi guys,
I'm a total greenhorn so please bear with me. I'm designing a circuit in which I use a lot of tri-state buffers. All ICs in the circuit will be powered with 5V, but I need to pass 12V (and up to 15A) from the input to the output of the tri-state buffers when the buffer is enabled...
