I need a circuit for opening a door's latch using IR LED switch. Please help.
Sir, I din't yet start working on it. First of all i need a model of it, that is what i'm asking you to help me with. Does the latching solenoid work on a 9v battery supply? And does the IR Rx and Tx require any coding?
Does the latching solenoid work on a 9v battery supply?
So, let me get this straight... You're asking us for detailed specifications for an unknown device that you haven't chosen yet?
In that case the answer is: definitely!*
*definitely maybe
If you're referring to what's commonly known as a '9V Transistor Radio Battery' then absolutely and unequivocally NO!
Chris
Okay, so what's the minimum voltage required for its working?
Unless this solenoid is unlatching a dollhouse door I don't see battery operation practical. To power a typical (human size) door latch for a reasonable period of time, without recharging or battery replacement, would require D cells or rechargeable Nicad, Lith-Ion, etc packs.

Okay. I need a circuit for the Remote controlling operation of the circuit, could you please post a circuit which works on IR and does a single operation(Opening of latch).
No! How can we provide information when we receive none from you?
Chris
Okay, what all information do you need? What i know is Astable multivibrator can be used as a 38Khz transmitter but i'm not sure if it needs modulation, and i don't know which IC to be used in the receiver.
The fact of the matter is the transmitter and receiver aren't an issue here There are numerous IR kits available that will be cheaper than building it by procuring the components individually ... and they come with the PCB!
Chris
Yes sir, i'm aware of that. But it's actually a college product, so it's kinda do it yourself type. So i need a practical working circuit for the Rx and Tx.
