In this project i am going to show A very useful and beautiful flip flop circuit with time IC 555. The circuit is able to blink 8 super bright blue and Reds LED’s. The circuit is build around a famous 555 timer IC which is wired as an a-stable multi vibrator here. The LED’s are classified in two pairs contains 8 LED’s. The no of LED’s can be increase and decrease according to your requirements and desire.
IC will blink each pair one by one or in a flip flop manner. A 10K variable resistor is used to adjust the flashing speed per.
