In the example circuit changing the values of R2 and R1 will change the on/off ratio and collectively the rate. You can play with these values to get even on/off or quick on/ long off or what ever you like. A larger calue of C1 will slow the flashes and a smaller will quicken. BTW: at 5V you will need a resistor in series with the LED start with 1K or the LED will draw too much current and burn out. |
