IR receiver with MCU

Hello,
I'm building a remote control to control my robot and I want to interface the IR receiver output with the MCU so that I can give the commands using my robot istead of switches connected to the MCU, but the problem is that the IR sensor doesn;t give 5 volt exactly so i have to put a capacitor to reach 5 volt to charge to reach 5 volt but that is causing problem with time
That causes delay to the MCU, So I think by that concept I can't send continuous pulses to give a certain command to the MCU
Can anyone help?
 
Check out my PIC tutorials, which include IR remote control.

There's no need for the input pin to reach 5V, and I'm somewhat bemused by your addition of a capacitor?.
 
It doesn't reach 5 volt, It's about 2.5 volt So I'm adding a capacitor to save voltage and reach 5 volt in three seconds or something

I suggest you post your circuit, you're doing something stange there?.

I presume you are using a scope to monitor the output?, you can't use a meter as it's a pulsed output, a representation of the original modulation.
