Driving an LED array with a 555 timer

(in response to comment at An LED Array PWM Dimmer with the 555 from Jason Oliver)

Attached i have the circuit that you need. The 555 timer is connected as an astable multivibrator. The circuit is shown and explained in details in this page:
The 555 as Astable Multivibrator

The 3 resistors for the LEDs are 37 ohms ( i forgot to show it in the schematic)
