Is this simple schematic electrically correct?

[sccoupe]

Will these do for the capacitor situation?

Cap 10uf

Cap .1uf


If these are not used at all, how does that effect a pic that is being used to count rpm pulses?

Thanks

Yes those caps will be fine, without them the circuit will be vunerable to electrical noise & may give unexpected results.

Also for the led resistor I would use around 270 ohms.
