In this project, DC motor control is provided by using an H bridge. The polarity of a voltage delivered to a load is switched using an H-bridge. These circuits are commonly used to allow DC motors to run forward or backward in robotics and other applications.

The main purpose of the project is to perform the functions of the buttons used for DC motor control with a delay of 1 second. To achieve this, Shift Registers were used. There are four Shift Registers. SISO Shift Register was used in this project. By giving a frequency of 4Hz from CLOCK in the SISO Shift Register, the frequency at the SISO output is reduced to 1Hz. Thus, the buttons perform their functions with a delay of 1 second.

In this section, the sub-circuits used in the project are explained.

D (or Delay) Flip Flop is a digital electrical circuit that delays the state change of its output signal (Q) until the next rising edge of a clock timing input signal occurs.

The D flip-flop follows the input. It makes transitions that match the input D. The D stands for "data,". It stores the value on the data line. It can be compared to a simple memory cell. By using an inverter to connect the set and reset a set/reset flip-flop, a D flip-flop can be created. It's possible to time the outcome. In this project, this property was used.

The internal structure of the flip flop is shown in Figure 1.

The IC D flip-flop can be seen in Figure 2.

Also, the truth table of the D flip-flop can be seen in Figure 3.
