How make OR gate project


1.Definitions

The OR gate is an electronic device which receives two inputs each in the form of a
binary digit, that is 0 or 1, and produces a binary digit as output, depending upon the
values of the two inputs. It is represented by the symbol shown in Figure 5.5.
A and B are the two inputs, and F is the single output. As high (1) or low (0) voltages
are applied to A and B various possible outputs are achieved, these being de ned by
means of a truth table as shown in Table 5.3. So, for example, if a low (0) voltage is
applied to A and a high (1) voltage is applied to B, the output is a high (1) voltage at
F. We note that a ‘1’ appears in the right-hand column of the truth table whenever A
or B takes the value 1, hence the name OR gate. We use the symbol + to represent OR.
Because it connects the variables A and B, OR is known as a logical connective.We shall
meet other logical connectives shortly. This connective is also known as a disjunction,
so that A + B is said to be the disjunction of A and B.



2.Name Component in Proteus


3. Schematic , PCB layout and 3D View





4.Real name and picture of Component that we need to use:

  • Diode 1N4007 = 3
  • Transistor BC547 or 2N2222 = 8
  • Resistance 1k=4 , 4k=2 , 2.5k=1 , 1.5k=1 , 150=1
  • Jumper or Tblock = 1
  • Button = 2
  • LED = 1

5.Process in production

  • First, we need to print it in powder
  • Get it on the board
  • Dissolve in acid
  • When it is done, drill it in the hole
  • Compose the component according to the drawn PCB
6.Test project

Matrix algebra

                 Matrices provide a means of storing large quantities of information in such a way that each piece can be easily identified and manipulated. They permit the solution of large systems of linear equations to be carried out in a logical and formal way so that computer implementation follows naturally. Applications of matrices extend over many areas of engineering including electrical network analysis and robotics. 1-BASIC DEFINITIONS                  Matrix is a rectangular pattern or array of numbers.      For example:                    are all matrices. Note that we usually use a capital letter to denote a matrix, and enclose the array of numbers in brackets. To describe the size of a matrix we quote its number of rows and columns in that order so, for example, an r × s matrix has r rows and s colu...

Barometric pressure sensor with Arduino

Hardware Required - Arduino or Genuino board - SCP1000 Pressure Sensor Breakout Board - hook-up wires  Procedure  Follow the circuit diagram and make the connections as shown in the image given below. Arduino Code /******* All the resources for this project:   https://lihuo.blogspot.com *******/ The code below starts out by setting the SCP1000 's configuration registers in the setup() . In the main loop, it sets the sensor to read in high resolution mode, meaning that it will return a 19-bit value, for the pressure reading, and 16 bits for the temperature. The actual reading in degrees Celsius is the 16-bit result divided by 20.   Then it reads the temperature's two bytes. Once it's got the temperature, it reads the pressure in two parts. First it reads the highest three bits, then the lower 16 bits. It combines these two into one single long integer by bit shifting the high bits then using a bitwise OR to combine them...
