How do I turn on LEDS with a IR remote?

I have a IR remote and about 20 LEDS that are hooked to a Lithium-Ion battery and I would just like to be able to turn them on and off with my IR remote. I have seen things for home lights but I have never seen anything on how to do this with low volt DC power. All I want to do is have it as a switch ON/OFF is all it really needs to be able to do. It doesn't have to be IR either, I just need a way to turn them on wireless. Thank you.

Short of looking into commercial options you'll want to look into using a micro controller like an Arduino to connect an IR receiver too. Then you can program it to read the signal your remote sends out and turn on your LEDS as needed.

Thank you I was looking into a Arduino but was hoping there was a more simple way that didn't require one. Do you know of any other ways to turn them on without actually touching or having something wired? I was looking into reed switches but there has to be other ways that don't require a button. I am trying to set up speakers in a helmet and wont be able to actually press a button in or on the helmet.

do you want them to all turn on or just each one individeley. i will supply an arduino code and wireing diagram. 20 leds right? arduino uno or micro would be best

If you take out the voltage regulator this circuit runs on 3 to 5 volts.

To use an IR remote or other wireless device to trigger the lights you'll need more than a simple circuit.

The LEDs have to be wired to a power source and some means of turning that power source on and off. Unless you are good with plugging in the power to turn it on and unplugging the power to turn them off. Otherwise additional electronics need to be added. Be it a physical switch or some form of wireless receiver.

Okay thank you for your help!! Do you know of a place where I can just buy something already set up for this sort of use? I saw some LED strips on ebay for motorcycles and cars that have a wireless remote that go to them, they run on 12v though is there a way I can find something already made like that and modify it to work with my LEDS and a lower voltage? Thank you!
There are RF remote control transmitter and receiver kits you can get like this one.

Connect the output to transistors. The transistors will act as electronic switches so when it receives a voltage from the output pin of the receiver it will allow power from your 5V source through to the LEDs. You may have to use a transistor latch circuit. The pins on the receiver are only going to send a small pulse when you hit the button on your remote. A transistor latch circuit will allow that pulse to turn the LEDs on and keep them on with a single button press on the remote. Then assign one of the other buttons to turn the transistor latch/LEDs off.

Thank you!! I think that will work perfectly!
There is a more simple way than Arduino.

I turn LEDs and motors on an off with remotes in this Instructable.
