Does my remote controll have an infrared LED?
924216
I am willing to bet (but am not completely sure) that the LED pulses, which can be interpreted digitally, to perform the different actions (how else would the TV "know" to adjust volume, channel, ect?). The universal remotes would simply have all those different coding systems preprogrammed into it (notice how you have to select one with a universal remote). You could probably figure it out for sure by probing the input trace to the LED with an oscilliscope and enter in various commands, but who has the time right?

Ive never really heard about infrared causing any health problems, but at the same time, it is radiation coming from those little things (miniscule if im not mistaken). I think you'll be ok as long as your not like, pointing the remote control at your eye and pressing the button day or night.

Hi. Sounds like you puffed the LED. Most need a resistor to limit current.

passive infrared detectors, solid-state cont actors, ultrasonic devices, and photosensitive controls at their disposal\n\n\n\nManual or automatic dimming equipment, which can respond to many inputs, allows the illumination of a space to be set at any desired level. The semiconductor used in a dimmer circuit is called a triac. The triac provides phase control, meaning that it regulates the current to the lighting load by only conducing during a selected part of the AC power cycle.\n\nIncandescent dimming devices include wall box-type units rated as high as 2,000W that can fit in a single-gang electrical device box. Some models allow dimming from two or more locations, which previously required a remotely controlled dimmer module.\n\n\n\nfor any further clarification, you can mail me

light sensitivity is a remote possibility, but possible none-the-less.\n\nBest to try it in the sun before laying under a light bed.

When configuring infrared, you can allow the computer to assign the interrupt request lines (IRQs) necessary to enable infrared by using the Auto selection for the Infrared Port type. However, this may lead to possible IRQ conflicts in some configurations. If needed, you can manually map the address of the infrared port to avoid address conflicts with other devices.\n\n \n NOTE:  If you change the infrared port address, be careful not to create a conflict with the addresses of the serial port or the parallel port.  \n\n\nSelect the method appropriate to the type of configuration you wish to use.\n\n\nAutomatic Configuration \n\nTo enable infrared in the BIOS for the Inspiron computers listed above, perform the following steps:\n\nEnter System Setup (BIOS).\n\nThe System Setup screen appears.\n\nHow do I enable infrared in the System Setup (BIOS) for my Dell™ Inspiron™ computer?\n\nOverview\n\n\nEnable Infrared on Inspiron 3000, 3200, 3500, 5000(e), 7000, 7500 \n\n\nAutomatic Configuration \n\n\nMapped Address Assignment \n\n\nEnable Infrared on Inspiron 3700, 3800, 4000, 8000 \n\nClick the links above for detailed instructions.\n\nAdditional Information\n\n\n\n--------------------------------------------------------------------------------\n\nEnable Infrared on Inspiron 3000, 3200, 3500, 5000(e), 7000, 7500\n\nWhen configuring infrared, you can allow the computer to assign the interrupt request lines (IRQs) necessary to enable infrared by using the Auto selection for the Infrared Port type.

It is usually best to set up Fast IR (FIR) when it is specifically needed for a device. Fast IR requires a DMA channel to operate. On most computers, the parallel port mode will need to be changed to bi-directional to free the DMA channel for infrared use. It is important to remember that speed increases will only be noticed with devices that are Fast IR (IrDA 1.1) compliant. Refer to the manual or contact the hardware vendor of the infrared device to determine if it is Fast IR compliant.  \n\n\nPress the <F10> key to Save and Exit.\n\nThe Setup Confirmation screen appears.\n\nPress the <Right Arrow> or <Left Arrow> key until Yes is

I have seen ATI stuff for some controls but...\n\nthe problem is in the monitor - you need to take the back off and find the right pots on the board and adjust them - carefully.\n\nI would suggest that if you do this - take the back off, that you have enough electrical training not to kill your self - and mark the settings before changing them so you can put them back if needed...

That just means the detector was most sensitive to infrared light.  It just depends on what material the detector was made of.

look for ir on your firewall or either fender.

If it came with software, then you could probably change the settings from there.  Or, you could just increase the light in your room where the webcam is.

check our pcdj.com they have a new lighting program for pc control with full dmx protocol\n\nits called " DMX"\n\nyou can program the lights to go with certain songs...etc,  its amazing!

it will be in your display settings under colour adjustment \nor some computers you can adjuct useing the keys just consalt your manual \nelse it may be the backlight that has failed if it is an lcd monitor

Sorry....that is not correct.  LCD's do NOT emit light.\n\n\nYou see LCD technology does not itself emit light. you either must have enough ambiant light to see, or it must be 'back-lit'. The Technology formmerly used to do this was CCFL or Cold Cathode Forescent Lamp, these failed in 2 different ways as they aged.\n\n1. the light would get darker as it aged. Some would even change color therby messing-up the colors the display rendered.\n\nand\n\n2. As the bulb ages, it requires more and more power to engergize it. Eventually it will reach a point where the amperage required to start the lamp, will exceed the capacity the circut it is on can provide and simply not light.\n\nIf you've ever seen this, or suspect that this is your problem (display won't light, or goes dark shortly after starting,) simply shine a bright light source directly into the display, you should see faintly whatever the desktop was diplaying at the time.....or your desktop if it never came on to begin with.\n\nCurrent Backlight technology uses white LED lights....far better.\nthe BEST ones use 3 LED lights....1 each of Red Blue and Green, much much better at displaying the full color spectrum.\n\nHope that helps !\n\nPS: the FLASHLIGHT you have.....is an LED flashlight, I would wager. I have one too, they're great !  $27 bucks though.\n\nPPS: more like 100,000 hours.\n\n\nto poster below....the current back-lighting method IS LED, the fact that it is also used in Thin Film Transister Displays does not really make a difference to this question.\ncheck your facts. oh and your 'plasma' info is waaaaaay off.\none year!  ha.

did you mean how does a light sensor work?

you could actually use the cable, you can also buy a cable tester, where you plug both ends in, run the test and some status LED's will give you the results\n\nhttp://www.maplin.co.uk/Module.aspx?ModuleNo=45778&doy=6m4&C=SEO&U=Template

if your camera have an infrared transmitter you can use it, otherwise do it the old fashion way, via USB cable

you can buy a universal remote control...
