4011 Dual Led flasher
This simple circuit uses NAND Gates to alternately flash two led's. The two 47uF capacitors determine the flash frequency. It is a good idea to use a decoupling capacitor across the power supply. I made this circuit using the components shown and it worked fine. The IC that I used is the 4011 Quad
2-input NAND Gate. If you have any questions about this circuit or any other circuit on my website then you can Email me.
