To build JK flip flop using NAND gates.

  Aim: To build Flip-flop (JK) circuits using NAND gates.

Material required: IC7410, A digital microcontroller(timer), A Breadboard, A Battery(5V), 2 LEDs, Connecting wires.

Theory: 

A JK Flip-flop is a type of sequential logic circuit used to store a single bit of binary data. It is an improvement over the SR flip-flop, designed to eliminate the invalid or forbidden state that occurs when both the Set(S) and Reset(R) inputs are high. Named after its inventor Jack Kilby, the JK flip flop has two inputs, j and k and two outputs, Qn and Qn bar. it includes a clock input (CLK) that controls the timing of state changes.

                                                                           The versatility of JK flip flop makes it a widely used component in digital electronics particularly in counters, shift registers and memory devices.

Procedure: 

1. All the ICs and other components were checked for defect.
2. The breadboard was set-up with the components as in circuit diagram.
3. All combination of input and output was verified from the truth table
   .

Result: Flip-flop (JK) circuit was built and verified using the NAND gates.

Precautions:

1. Make sure the apparatus is not defective.
2. Make sure connecting wire is not loose.
3. Never touch live wire.
