“In this Instructable I show you how to make a Flip Flop LED circuit. The special thing about this circuit is that it does not use an IC (Integrated Circuit).
By using different resistors, capacitors and transistors, I succeeded in this project to make a circuit that lights the LED lights one by one.
I will explain how the circuit works in the last step.
2 LED lights (any color you want)
2 BC547 transistors
2 470 Ohm resistors
2 10K resistors
2 100 uF capacitors”
