Converting 5V DC to AC: Is It Possible?

[omidomid]

Hello, I'm trying to convert a simple 5v DC source to AC using the simplest method possible. The project I'm trying to do involves a 4-bit counter that requires a clocked source, so I need to be able to specify the frequency. Is this possible or can anyone help?

The simplest oscillator for this is the Relaxation Oscillator:

You can also use the classic 555 timer chip and follow the datasheet or the application notes for it:
