This video is on how to make a remote control circuit out of a lego IR transmitter and IR receiver. Other methods of making remote control circuits can be very costly. Using Arduino’s can be expensive, because two of them are needed. This method is taking apart a lego IR receiver, and isolating the DC in and out wires, it is then possible to power other things remotely. There are many possibilities that can be done with the circuit. One could potentially hook up a relay to the circuit and control anything they wanted remotely.

  1. I know this is an old video, but I would still like to ask, please, I have an old TV remote that works, but the TV died years ago. Is it possible to use that remote to make a receiver for changing for example the inputs from my sound switcher box. Thank you.

  2. It will be a lot cheaper using ardiuno. Ir will be cheap and even if you have go for RC you can buy NRFL01 2.4ghz transmitter and reciever for 2 dollars!!!

  3. I liked the project but when I clicked on the link I couldn't find the place to sign up. The link just kept bringing me back to the sign up page with no place to put my info into. lol

  4. Dude you have no idea what your doing do you? You strip wires with a fucking needle nose and you DONT test a circuit by "touching" it to the battery to check for polarity,, thats a good way to fry the circuit. Its called use a fucking multimeter to check for polarity.

  5. Would this "thingy" work to simply close the circuit to small external computer speakers? It seems that it provides batt. power to the circuit which is unwanted for my app. Thanx. Gb bg

  6. hello sir..
    i like your video…
    i want to make rc control skateboard. .
    can i able to operate skateboard dc motor with this two rc reciever and controller? ?

    or this rc reciever and controller …only use for small toy car?

    please give me suggestions. .

    please reply

  7. Please what are the important components used for remote circuit? How can one get or make it. This is the real question. Thanks.
