How to build a data flip-flop and a JK flip-flop using individual transistors will be discussed in detail. The flip flops are triggered by a clock which, in this case, is an astable multivibrator. The inverted clock output is sent into the trigger which is then sent to the input of the flip flops. Push button switches can also be used to toggle the set, rest, J, K, and data inputs. The output of the clock, trigger, and data flip-flops are displayed on an oscilloscope to help show how the flip-flops work.
