Ir remote that activates 3 leds. Answered
Hi, guys. I need some serious help. I need to build the following device:
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.
