Automatic Toilet Flusher

Hey Pic_User or anyone

Is it difficult to interface the that link that you gave me to a pic?

All I want it to do is when it comes in contact, to rotate the servo all the way to the right or all the way to the left.

Hi Techbuilder,

Mostly it looks like it will operate with 5V DC input.
It has “open collector” output.
It has a built in 10k “pull-up” resistor.

so it LOOKs like you could use a circuit like this:

Thanks, would it be hard to compile a code to detect using this method?

Hi Techbuilder,

You could consider the module like a push button. Your program would need to watch for a low or 0 (zero) to know someone / some thing had come close to the sensor module.

Ohh ok

I get it

So if I want to change the range to about 6 inches would that be done by changing the resistance to the IR leds?

[Pic_User]

That web page said "approximately 15cm". I had to use an on-line calculator because I am an old phart, and it said almost 6 inches (5.9").

Cool

thanks I appreciate it

and I appreciate everyone else helping me

Well I am going to order that Sharp IS471FE and then write a program
well try and then post my progress.

Thanks everyone
