Perhaps Portb.1 is damaged(from 9V??? through the servo???) if only LED2 works as expected.
Test by replacing LED1 with LED2 and vice versa in your program.
Or try to move LED1 to another pin e.g. portb.5 just in case portb.1 is not correctly configured(depends on PIC as some pins do other things as well).
Remember to change the TRIS register also.

Portb doesn't see 9 volts if you took a look at my schematic it has a separate power supply.
The potentiometer is what connects to the pic from the servo.

One LED works as expected. The sensor and PIC work together. The code looks OK.

Are you by chance missing an IR LED? Maybe that is the one not lighting, or on the wrong pin?

No everything is there and facing right

The only thing I can say to try now is a different pin for the LED that is not working (or a different chip ) you could have a bad one.

Sorry I can not be of more help.

No it's not your fault

I will try with just a regular switch and then see what happens

What resistor should I use for connecting a switch to a pin?

[mackrackit]

I use a 10K normally. Higher - more resistance- is fine if you do not have a 10K.
The PBP manual under the BUTTON command has a schematic.

Cool thanks

I saw this and thought about your project.

A few modifications and...well they would have to be trained to put the lid down.
