LED Traffic Light 555 IC Timer Breadboard Video



Fun electronics with 555 timer chip, running off 9-volt battery and 10-volt 100 uF capacitors. Experiment with resistor values interfacing with the 555; instead of 47K ohm resistor, I’m using 22K, which blinks the yellow light longer. Links to info and tutorials:
