can i use a Timer IC chip with an arduino?

Projects General Guidance
1

i have a couple Timer IC chips lying around, and i was wondering if they would be useful for any projects with arduino...

how could they be used in an arduino project?

Not much a timer (555?) chip can do that an Arduino can't do better.

Could be set as a digitally controlled oscillator.
Put out a filtered PWM output to 555 pin 5 I think, use that voltage to get wider range of frequency from the 555.
I wrote to WillamK about that a while back.
Maybe use another output to create an envelope to control the 555 oscillation, make different sounds.

I'm going to steal Terry King's thunder XD and mention that a 555 works well as a gate driver for a mosfet or for general purpose sourcing/sinking of more current than the Arduino's pins are capable of.

Maybe you should give a part number before everyone jumps to a conclusion.

Edit: oh, too late. Still, an actual part number would be helpful.

I wonder if the OP means something like the Dallas RTC ICs or something...?

part number is 555 and a 556
