10 LED Sequencer with a 555 and 4017
Notice that by placing the LED where the resistors are, you can get away using only one series limiting resistor for all 10 LED's.....
And there should be a 10nf cap on pin 5 to ground.



120VAC LED Voltmeter and Current Meter
Documentation poor, not sure where to connect input voltage, and what voltage it should be, or if it is the voltage you are measuring....
