Boolean Algebra - Simplifying to two different expressions. Last Post Jan 20, Replies 12 Views Creating instances of a class in Objective C. Last Post May 17, Replies 9 Views 2K.Boolean algebra is the branch of mathematics that includes methods for manipulating logical variables and logical expressions. The Boolean values are represented by using logic values 0 and 1.

The basic laws used in Boolean algebra are commutative law, associate law, distributive law, identity law and redundance law. So the Boolean algebra calculator is used to perform the logical operations such as conjunction, disjunction, implication and equality. These operations can be stated in the following ways:. The truth table can also be developed with the use of connectives.

Boolean algebra simplification calculator is an advanced calculator that immediately gives the result in the form of a math expression by performing the operations, such as multiplication, addition, etc. The Boolean calculators are free to use and are the most compatible with any computer compared to a regular calculator.

The operation of this Boolean algebra simplifier calculator consists of different blocks such as power supply, microcontrollerLED display and keypad.

Power Supply Unit: The device that supplies electrical energy to one or more loads is known as power supply, and — in the same way, it converts other forms of energy like mechanical, chemical, solar energy into electrical energy. In this project, the power supply is about 5V, and it is given to the microcontroller, keypad and display.

Micro Controller: Microcontroller reads the data from the keypad and sends it to the display unit. Here, the microcontroller acts as the brain of the project, which is programmed in keil software.

So, these Bi colors represent the normal and complements of the variables. Like switches, the keypad in this project — which gives the min terms as input, i. This is a low-cost, low-power, portable, reliable and fast performing calculator that is built by the simple available component in the market like resistors, keypad, LEDs and microcontroller as shown in the figure.

The circuit is a simple three-variable minimizer that uses the Quine MC Cluskey algorithm and finds minimum sum of products by implementing Boolean functions.

Boolean algebra calculator simplifies the logic functions and Boolean expressions by using the laws and theorems that are implemented on this algorithm. The microcontroller plays a major role in this project which is coded with this algorithm and controls the other components used in the circuit.

When the power is switched on, the LED glows indicating that the microcontroller is ready to take the inputs as min terms provided by the keypad, and these Boolean expressions are given in the SOP Sum of Products form.

Here, we are using 9 switches on the keypad, among them, 8 switches correspond to minterms that performs the product operation, and the 9th switch is used as the next button. After entering the expression, the LED gets off, and the microcontroller reduces the minterm expression, based on the algorithm; and then, the input LED glows which means that the expression is minimized, and it gets displayed.

The output is displayed as one min-term at one time, and the next min term is displayed by pressing the next button, so after reaching the last min term, the expression gets reduced, and the input LED switches off which indicates that the output gets ended. After that, the LED automatically switches on indicating the microcontroller is ready to take the next input. For better understanding of this concept, here, we are giving some Boolean algebra simplification examples. From the logic diagram, truth table expression is simplified by using De Morgan theorem.

Here, this original form that involves the sum of products and common factors is eliminated by using the single variable theorems. By applying the identity rule and factorization final, the expression gets simplified to a simple form.

This is the application of Boolean algebra that performs the Boolean operations in the circuit for opening and closing a door or moving up or down the elevators. To perform these operations, three inputs are needed in the first floor and the second floors. Therefore, pushing the button represents 1, otherwise zero, and these buttons are placed in the elevator both inside as well as outside. By implementing the Boolean algebra operations in the main controller, the elevator can perform the desired operation.

The Boolean algebra can be applied for implementing simple vending machine wherein the selection of Coffee, Tea and milk options is based on customer choice. The pressing of buttons corresponds to the logic 1 otherwise logic zero.

So, based on the given inputs, the logical operations are performed and the output is obtained. He has 8 years of experience in Customer Support, Operations and Administration.

Please get back to us at info edgefxkits. Thankyou for introducing the new project on Boolean Algebra Calculator. I need full details about this project including microcontroller program as i want to implement this project.This circuit is a simple 3 variable Boolean expression minimizer. It uses the Quine McCluskey algorithm which was described in the chapter 1. In this the microcontroller plays a major role, it consists of code to implement the described algorithm as well as controlls other components in the circuit.

Initially when the power is switched on an LED will glow which indicates that the microcontroller is ready to take the input.

Here the input boolean expression is given in SOP form, i. The keypad consists of 9 switches of which 8 switches corresponds to one min-term each and the 9th one is used as next button. After entering the expression the input indicating LED will go OFF, now based on the algorithm microcontroller reduces the expression and the input representing LED glows which means that the expression has been minimized and is displayed.

The output is displayed as one min-term at a time, next min-term is displayed by pressing the next button and after reaching the last min-term of the reduced expression the input indicating LED is switched OFF which represents end of the output. After few seconds it is again switched ON automatically when microcontroller is ready to take the next input. Your email address will not be published.

For mo Add Teacher Note. Did you make this project? Share it with us!Boolean algebra is a special branch of algebra which is mostly used in digital electronics. Boolean algebra was invented in the year ofby an English mathematician George Boole. Boolean algebra is a method of simplifying the logic circuits or sometimes called as logic switching circuits in digital electronics. A Boolean function is a function which represents the relation between the input and output of a logic circuit. Boolean logic allows only two states of the circuit, such as True and False.

The most important thing to remember in Boolean algebra is that it is very much different than regular mathematical algebra and its methods.

Before learning about the Boolean algebra, lets us know about the history of Boolean algebra and its invention and development. As mentioned earlier, Boolean algebra is invented in the year ofby an English mathematician George Boole. After this, the Boolean algebra is well known as the perfect way for representing the digital logic circuits. In the late 19th century, scientists Jevons, Schroder and Huntington used this concept for modernized concepts.

And in the year ofM. Boolean Expressions These are similar to that of the mathematical expression. The Boolean expressions are formed by combining the logical variables by using the logical operators. For example. There are some basic laws and rules that the Boolean algebraic system must follow. The basic Boolean arithmetic operations are of 3 types. Always, we represent the Boolean operation in capital letters.

Representing the operations in lower case letters is a wrong way. Boolean algebra supports the complementation law. For example, if the variable is 1, then its complement will be 0.You seem to have CSS turned off. Please don't fill out this field.
