4011 Dual Led flasher


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.
