hi,

Can any one tell me how can I build a 5V pulse generator by using 12V DC supply?
It just a simple continues pulse generator. The frequency is between 1KHz to 5KHz.
 
Search google for 555 timer and 7805 regulator circuits.

The 7805 drops the 12volts to 5 volts, the 555 timer will generate your frequency.
