I want reed switch to automate the curtains of my conference room. when the projector screen is pulled down, the curtains should be drawn. I will place a magnet on the lower end of the screen which would trigger the reed switch which in turn should trigger the motor. Is it possible to do so using a reed switch? If yes the please let me know how to make connections and which controller will b e most suitable to use and easy to program.
yes, with a '51 place the reed switch between e.g. the int0 pin and ground
i do not think the '51 will be fast enough to sense it. even the super turbo ones. what if someone pulls the screen down very fast?
the i.MX 6Quad is quite fast and he could control more than one curtain with it.
he must think about using Linux to do the job.
Erik's humour chip is broken, the answer was clearly satirical.
satirical, maybe, but correct.
Using linux to 'see' a reed switch is TOTALLY RIDICULOUS
i do not think the '51 will be fast enough to sense it. a typical '51 will need <= 1us to 'see' int0, if the person that has no idea about what 'enough' is does not believe that 1us is a 'guaranteed' close of the reed switch in this application, I have some swampland in Florida to sell.
of course you can hammer a thumb tack in with an anvil, but even a shoe will do.
