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 :)

Where could I buy a simple wireless ON/OFF switch?

I'm looking for a simple, small, wireless switch. you know if I press a button, a few feet away a circuit will go from open, to closed. IR preferably, I mean the remote on a remote control car can tell the car to go forward, there must be an even simpler device. Please and thanks!

How can a camera work if it films IR? Answered

If you film a remote control while pushing any button, you can see purple flashes of the IR LED, so most cameras can film IR. Why don't we have problems taking photos of hot things (people, boiling kettles, soldering irons, etc)? If I knew how to add a video I would have done it.

Ir remote that activates 3 leds.

Hi, guys. I need some serious help. I need to build the following device: Remote control Ir transmitter with 3 buttons. Each button activates different led of different colours 1 button) red 2 button) blue 3 button) green A receiver device that acts in a different way for each button 1 button) red led lights for 3 seconds and there is a beep.  2 button) blue led turns on and turns off only after 5 minutes. 3 button) when third button on remote is pressed, then on a receiver device green light turns on, and turns off when the button is released. 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.

Wanting to make a switchable IR night light

Every night I come home, I have to open my garage door manually and park my motorcycle. When the garage closes, its dark and I tend to bump into my cycles exhaust burning myself. Yeah pretty funny. Anyways I had an idea, since I already had an arduino uno board and an IR Sensor and emitter, I wanted to make a trigger-able light switch. But I wanted my IR reader to run on AC, like a night light. At the press of a button from my emitter, the IR would pick up the codes and my light would turn on. Is this possible? Some people say, just buy a motion sensor and plug it in, I say i'll just salvage it for parts and try to make my own. Whats the fun in buying it, when I could build it with parts I already have. I mean, I know AC is dangerous, if not viable, then I could resort to a 9v with a power capacitor so long as it doesn't drain my 9v instantly.
