I have a project, and im going to use some kind of a remote controll. I know that this may not be your expertise, but maybe someone can help me :P ?

the idea is that i have some kind of Infrared diode to send a signal to a receiver, and then to the microcontroller. but i haven't done much of sending signals trough the air;) so what should the receiver be? and how can i convert this to a 1 or a 0, so the microcontroller can know the differense when the button is pushed, and then not? some links or hard facts would be nice :D

Hello,

Well, I didn't have the energy to write a a proper description on how to do this. There are, however, a few pages where you can find information on this topic.

The following site gives a descent explenation and a program example for Atmega162 and AVR-GCC:

The decoder used is the TSOP1736, and the datasheet is found here:

Hope it helps!

One of several donated projects on this topic is
https://www.avrfreaks.net/index.p...

It starts with a $4 IR receiver - this is an IR photodiode, and a carrier frequency (say, 38KHz) bandpass filter and high gain amplifier. WIthout this, you have a 3 inch range system that doesn't tolerate sunshine.

Some leds will allow you to pulse them with several AMPS of surrent, for microseconds---if you need to go a long distance. Have done this for a remote that had to work several hundred feet outdoors in blazing summer sunlight!

When in the dark remember-the future looks brighter than ever.   I look forward to being able to predict the future!
