IR Receiver

I recently ripped apart a Sky+ box that was out of use. Of course, it contained many parts. Quite a few tact switches, a few LEDs, a lot of capacitors, lots of resistors. One of these parts was a little metal cube with a black sphere protruding from the front of it. This is the IR receiver for the remote. I wish to incorporate it into another project. The first problem is I don't know how to use it. It has 3 "legs" - 3 metal contacts. The second problem is I can't easily experiment with it as I inadvertently destroyed my breadboard earlier. A new one will come as soon as I can manage, but until then..... My question is this - any ideas how it would be used? Thanks in advance,     ~H4ZZ

IR Cake.

Hello, Some friends asked my wife to do a birthday cake for a girl of eight years. With her ‹age she is crazy about princesses. Well, what came to mind was that despite having done many projects with Arduino i had never applied electronics in a cake. So we decided to join forces and add some light (RGB LED) and movement (DC motor controlled with an L298) to the cake. Here is the link to the video: http://www.youtube.com/watch?v=TmL1nR2-uEQ&feature;=youtu.be

How can I receive IR signal and send it trough wires? Answered

 I want to place a device inside a close enclosure. The device in on warranty, so I don't want to take it apart. The device works with a remote control, so I was wondering if there is an easy way to mount another IR receiver that  will pick up the signal and sent the to a IR emitter via wire. I can't place the device close to one of the sides of the enclosure and open a hole for the IR receiver.  I hope make sense what I'm trying to do. Thank you for your help in advance.

What would be the best IR receiver for 980nm IR laser 0-15KHz

Dear enthusiasts, please help me out. What would be the best IR receiver to use for detecting signal from 980nm IR laser 0-15KHz. I'm going for distance here. 200 meters is more or less the goal. The further the better. Ambient light might also be an issue as this is to be done outside in possibly sunny conditions. If anybody has any ideas or suggestions please, throw them out here. Thanks.

How to check, if the IR sensor (from remote control) is working ???

Hi ... I would like to ask, how I could check, if the receiver (for remote control) is working. I bought on Ebay a used SCART FREEVIEW adapter ... but unfortunately it doesn't work (properly). I'm able to power it up, to see a picture = big logo IKASU. And at the beginning a small pop up menu appears and ask me, if it should start to check for channels. After few seconds it disappears and that's it ... I can't do anything else. There is just the logo :( I check the cables, of the receiver - there are fine, not broken. The RC seems to send signals as well (checked with camera if the IR led lights up). Do you know, how I could check, if the IR receiver works ??? There are 3 pins going out, from the receiver.

How to make a circuit with an IR receiver turn on with an infrared remote control?

We are currently having a Research project in our English class and we thought it would be nice if we tried a research regarding electronics because me and my parter are both interested in electronics.  However, we are both beginners when it comes to electronics. Is there anyone who can help us with the following: A. Building an IR remote that can send a signal to the IR receiver to momentarily turn on (kinda like a push switch) B. An IR receiver that will be connected to a circuit to allow it to momentarily turn on or off based on the actions of the IR remote C. A fabric/system that could give a sudden "shock" to the holder when turned on kinda like the gag shock pens. D. Schematics for the IR receiver circuit I don't even know if this project is plausible but if anyone could help, we extend our deepest gratitude :)

Question by tinovonga    |  last reply


IR Switch. Will this work? Answered

Hi Guys & Girls Obviously, i am new to this and my electronics knowledge is very limited. Let me first explain what my desired outcome is and then proceed with the questions i have. In the schematic below i connected two circuits that i found. One is a infrared receiver and the other a flip flop. With that, the following needs to happen : when the user presses a button on a IR transmitter aimed at the receiver circuit in the schematic it is sent through pin 3 to the flip flop circuit which in turn puts the relay in a (permanent) ON state. When the user presses the same button again, the process is repeated and puts the relay in a (permanent) OFF state. So bottom line a 1 button/channel IR press on press off switch to switch my 12v circuit on/off. Here are my questions: 1. Is the receiver circuit correct as i have drawn it i.e. will it work? 2. Is the flip flop circuit correct as i have drawn it i.e. will it work? 3. Where i have the red circle : 1. Is the connection between the receiver and flip flop circuit there correct? 2. Do i need another resistor there? 4. Do i need a “floating resistor” as a R5 around the relay and how does the practical application of this look (on all the diagrams i look at it’s drawn around the relay going from an input to an output on the same wire......does that mean that on the pcb it will run parallel between the “pos+ and neg-“ going into the relay?) 5. Is my relay connection correct within the blue circle? 6. All and all, put together will my circuit work as expected? I know there are probably a whole bunch of ways to achieve the result i am looking for and being a noob, this might be the most impractical(i don’t know), but the reason i went this route is because i have these components available to me and if at all possible, i would not want to go and buy other components. Thanks in advance for any help provided. I find it much easier to learn by building the circuits and then seeing with a multi meter etc. what the effects of each component is than reading through all these books and trying to cram everything into this thick skull of mine  Schematic Component Values : R1 = 220k ; R2 = 100k ; R3 = 10k ; R4 = 10k ; R5 = ? C1 = 1uf ; C2 = 0.01uf ; C3 = 10u Rx1 = Any tsop/similar U1 & U2 = 555 timers

PC IR Mouse/Controller

Hello everyone! I'm looking to get some advice on how to build a Wii-style controller for my PC. What I want to get it to do right now is just to move the cursor around on-screen, however I want to eventually turn it into a gun-style controller for use in shooter games. Anyway, I was wondering what the best way would be to track the movement of the gun (i.e. aiming). My idea was to use IR emitters in the controller and place 4 receivers at each corner of my monitor, which would all be hooked up to the Arduino. Then, I would use the data from the receivers and the strength of the signal on each receiver to calculate that into a position on the screen. The main problem is that I don't know how to measure the signal strength from each receiver, or even if this is possible. Also, if anybody has a simpler solution (other than buying a controller   ) please post. I sometimes like to over complicate things

How to program the decoded data received by an IR sensor in arduino?

I need to use the decoded data to turn on/off LEDs. I already have the command and control codes of the IR transmitter I am going to use. IR sensor is TSOP1738 and transmitter will most probably be a remote using RC5 protocol. The thing is I dont know how to program the decoded data from the sensor. This data is need for me to turn on/off LEDs. Its like if switch 1 in the transmitter is pressed LED1 should glow. If pressed again it should be off. Likewise for 3 or more LEDs. I am using an arduino board with ATMEGA8 on it.

Can I have help understanding this schematic? Answered

I am in the process of building an infrared motion detector. I've finished the infrared transmitter but I haven't been able to start on the receiver yet because the schematic has confused me. One part of the circuit, on the lower-right of the corner, appears not to be connected with the rest of the circuit at all. Until I understand how the two parts interact with each other, I can't continue building. I am still something of an amateur when it comes to solid-state circuitry; maybe someone who's more experienced will know what this means? Thanks.

I have a LED i cant light, no matter what. It has a little black dot in it. What kind of LED is that? Answered

Appearance: It is a common 5mm, transparent case, LED, being different from all others only by having this very tiny square dot over its anvil, kind of covering the reflexive cavity where the semiconductor (i don't know which) gets lit up. Other: I could not light this LED whit voltages from 1.5V to 3.5V. =O It came out of a photocopying machine, and was paired with an IR LED in some kind of emitter-receiver set. Other components of this set were a pair of smd resistors and a smd trim pot. Would it be and IR receiver or photodiode? UPDATE: I've took some photos of the mysterious LED. BUT, as no macro-enabled camera was available, i had to do the ghetto-way of photography. Soo: i have photos of it compared to the IR LED, and some photos of both anvils (IR, unknown), at 200x magnifying. Here they are. BTW, i hadn't tested the suggested circuits yet. =(

Also i need IR beam to be as thin as possible. On a distance of 1-10 meters its diameter must be something like 30cm. Is that possible?  Also how can i restrict IR beam to work only up to 10m distance. Also the problem is that i am restricted to 15$ budget, cause i need to build  60 pairs. If this is impossible for this budget i need the following: Remote control with 3 buttons. 2 buttons activates corresponding led for 3 seconds. third button activates third led only when pressed. The same thing with the IR beam diameter.
