Automatic Toilet Flusher

Maybe this can work better in case it is only code problem
Loop:
If IRLED1 =1 then
for a=1 to 100 'allow several pulses for the servo to reach the requested position
Pulsout 0,140 'could be 100=1ms to 200=2ms
pause 10
next a
else
pulsout 0,150 '150=1,5ms middle position
pause 10
endif
Goto Loop



Also check your servo if it is damaged since you power it with 9V instead of the usual 5V most RC servos work.

Thanks

I appreciate it

Although the servo was modified along time ago for continuous rotation,
Although it still works

5volts is actually low for a servo, that's the lowest amount of voltage you can imply.
In the book I own PIC basic projects
it has a servo page and it states that servos can run from 5vdc to 9vdc and 5volts was not recommended.

I tested it out and it works fine

I believe for it to be the sensor

Post the code you are currently trying.

Write the code to make a pin high or low output. No pulses for testing and use an LED instead of the servo.

What is the voltage at the sensor out put when connected to the PIC?

[Techbuilder]

Doesn't RBO and RB1 and so fourth supply 5+ to the pin?

Yep, at roughly 25mA per pin, at MOST! Try to draw any more than that, and you'll end with a pin that won't supply squat.

In your case RB0 is an input so it is looking for 0 volts to 1.2 volts for a LOW and 3.6 volts to 5 for HIGH. It is best to use a pull up or pull down resistor so the pin will be 0 or 5 and not floating around. Another part or two but I like using external pulls and not rely on the internals.

So, when the sensor is sending its high signal to the PIC and connected to the PIC, what is the voltage.

Try making the pin high or low with out the sensor.

Ok so I tried it with an led and it was working so I am guessing it is the servo
the potentiometer must be broken in the servo

When I get the new servo in the mail I will try it out

thanks everyone

by the way once everything works I will put up a "How to" for this automatic toilet flusher
once I am done.

Just in case anyone else wants to build it

[mackrackit]

Glad you found the problem!

Just curios, what servo are you using?
