Automatic Toilet Flusher

[Jerson]

Hi everyone maybe you can help me out
Here's what I have an idea of what I need

1 servo

1 Pic micro controller 16F627A

1 Ir receiver

1 Ir led

and I already know the resistors and caps I need.

Should I go with a different approach for programing or do you think that this sounds like a pretty solid toilet flusher?

Well, you seem to be on the right track except that you need a solenoid valve to make this viable. Instead of the servo, you fit a solenoid valve in series with the flush outlet; of course you have to remove the manual flush valve. This will work on a direct inlet pipe only. No cisterns here.

The other 'political' approach is to do what my little kids do. "If you don't flush, next time, I will not flush"

I wouldn't need a solenoid if I have the servo

Here's how the servo is

(it's a rough sketch)

Hi Techbuilder,
A regular hobby servo actuating the flush handle, may not have enough torque. I guess the force needed depends upon the toilet model.

Handle only requires 1 to 2 pounds to press down
And a hobby servo can do that easily.

That's why I decided to go with that

If you think a servo will work, why not try it out? I have a hunch though ....

I tried it yesterday and it flushed
but I had it connected to an RC Receiver instead of a PIC.

I just need help with electrical not mechanical (got that working yesterday)

I just wanted to know since I am a beginner at PICs

if it would be easier to do it with the Sharp GP2D12
or IR receiver and IR Led.

Now I know the Sharp is easier but how difficult would it be to make a program
with the IR receiver and IR Led?

I think I would move. Anyone who fails to flush may well fail to wash, and then handle your dishes, food etc . . . Opinions are like . . .roommates, some of them just do not wash . . . If you are really determined to do this, a car lock servo would be concealable in tank or behind it pulling up on the flapper, or use the servo to turn a shaft which has a string or cable . . .
