I have a remote control. Its very simple. When I press the switch, the IR LED sends a pulse sequence. Just like normal remotes.
Now I need to modify it such that.
I need to make a device which takes 2 wires as input.
When the wires are shorted, it activates the switch once.
Its different from the current setup, where continuously pressing the switch makes the IR led send pulse sequences continuously.
I want to
1. IF the switch is pushed to on - Send one pulse
2. If the switch is kept on for more than 2 seconds - Send another pulse when switch is disengaged.
So Lets say
I push switch and release it.
IT should work just like a normal remote
If I keep switch on - It should activate it just once
If switch is kept on for more than 2 seconds, then send the signal again when switched is moved to off position.
Any idea about a compact circuit implementation of the same?
