I Sine Wave Generators Square Wave Generators Logic Clocks and Oscillators Flashers To determine the resistance to be used for the LED current divide the supply voltage by the current required in mA .( 10mA = .01A) This circuit is the same as shown above in the Logic Clock but with the supply and LED added. Both IC's can be used and have the same pin connections
