This is an example on how to utilize a dual flipflop switch IC, in this case the C4027. In this example we only utilize a single switch, but this IC is a dual switch and that means that we can also connect the rest of the pins 9-15 and create another switch.
Below you will find the circuit schematics and list of parts for this setup, and also a video showing step by step how to build the circuit on breadboard.
IC1 – C4027
R1 – 330Ω
R2 – 10KΩ
C1 - 1uF
L1 - LED
S1 - MOM ON Button
