Interfacing Stepper Motor with 8051Microcontroller
In this section, we will see how to connect a stepper motor with Intel 8051 Microcontroller. Before discussing the interfacing techniques, we will see what are the stepper motors and how they work.Stepper MotorStepper motors are used to translate electrical pulses into mechanical movements. In some disk drives, dot matrix printers, and some other different places the stepper motors are used. The main advantage of using the stepper motor is the position control. Stepper motors generally have a permanent magnet shaft (rotor), and it is surrounded by a stator. Normal motor shafts can move freely but the stepper motor shafts move ...
Read MoreWhat is the difference between DFA and NFA?
DFA is the short form for the deterministic finite automata and NFA is for the Non-deterministic finite automata. Now, let us understand in detail about these two finite automata.DFAA Deterministic Finite automata is a five-tuple automata. Following is the definition of DFA −M=(Q, Σ, δ, q0, F)Where, Q : Finite set called states.Σ : Finite set called alphabets.δ : Q × Σ → Q is the transition function.q0 ϵ Q is the start or initial state.F : Final or accept state.NFANFA also has five states same as DFA, but with different transition function, as shown follows −δ: Q X Σ ...
Read MoreHow to Add Quotes around Numbers or Text in Excel
Have you ever wondered how you can add quotes to the text or words in Excel? Adding quotes is similar to adding symbols as prefix and suffix to the words. It can be done using the "format" function in Excel. In this tutorial, we have provided a detailed step-by-step explanation of how you can add quotes around numbers or text in Excel. Adding Quotes around Text using "Format Cells" Option You can use the "Format Cells" option in Excel to add quotes around numbers or text. It is simple process. Step 1: Let us suppose we have an Excel sheet ...
Read MoreHow to calculate standard error of the mean in Excel?
This same standard error would be a crucial statistic that serves as a parameter. But are you able to determine it throughout the process of sampling and distribution. A standard error of measurement, often known as the SEM, is indeed a statistical measurement which also provides an approximation of the difference between both the sample mean of the data and the actual population mean. You are aware that the Standard Error is equal to the Standard Deviation divided by the Square Root of the Total Number of Samples; hence, we can convert this into an Excel formula by writing Standard ...
Read MoreDifference Between MBR and GPT Partition
On Windows-based PCs, MBR and GPT are two prevalent partitioning techniques. They are layout specifications for storage devices such as an HDD (Hard Disk Drive) or SSD (Solid State Drive). The partition style instructs Windows on accessing the data on the present drive and is selected during disc startup. As a result, having a partition style for each disc in use is required. The partition styles MBR (Master Boot Record) and GPT (GUID Partition Table) are used to start a hard disc. MBR is the most common format and is compatible with BIOS systems. GPT is a newer type that ...
Read MoreAccess and trunk ports
Introduction In computer networking, a network switch is a device that connects network devices together to enable communication within a network. Switches are an essential component of any modern network, and they provide a way to manage network traffic by directing data to appropriate device. Access and trunk ports are two types of ports used on switches to manage network traffic. In this article, we will discuss access and trunk ports, their differences, and when to use them. What are Access and Trunk Ports? Access ports and trunk ports are two types of ports used on network switches. Access ...
Read MoreInterfacing DAC with 8051 Microcontroller
In this section we will see how DAC (Digital to Analog Converter) using Intel 8051 Microcontroller. We will also see the sinewave generation using DAC.The Digital to Analog converter (DAC) is a device, that is widely used for converting digital pulses to analog signals. There are two methods of converting digital signals to analog signals. These two methods are binary weighted method and R/2R ladder method. In this article we will use the MC1408 (DAC0808) Digital to Analog Converter. This chip uses R/2R ladder method. This method can achieve a much higher degree of precision. DACs are judged by its ...
Read MoreHow To Count Number Of Leap Years Between Two Dates In Excel?
Excel is a powerful tool that is commonly used to manipulate and analyze data, including dates. One common task is to determine the number of leap years between two given dates. Leap years occur every four years, with the exception of years that are divisible by 100 but not by 400. This can make calculating leap years a bit tricky, but fortunately, Excel has built-in functions that can help. In this tutorial, we will walk through the steps of how to count the number of leap years between two dates in Excel, using the functions and formulas available within the ...
Read MoreDifference Between RISC and CISC
RISC and CISC are two different types of computer architectures that are used to design the microprocessors that are found in computers. The fundamental difference between RISC and CISC is that RISC (Reduced Instruction Set Computer) includes simple instructions and takes one cycle, while the CISC (Complex Instruction Set Computer) includes complex instructions and takes multiple cycles. Read this tutorial to find out more about RISC and CISC and how these two architectures are different from each other. What is RISC? In the RISC architecture, the instruction set of the computer system is simplified to reduce the execution time. RISC ...
Read MoreDifference Between Microprocessor and Microcontroller
Both microprocessors and microcontrollers are types electronic devices that come in the form of integrated circuits (ICs) and are used in different modern electronic equipment such as computers, laptops, washing machines, air conditioners, and many other automated electronic gadgets. The primary function of both microprocessors and microcontrollers is to automate the processes. Read this article to find out more about microprocessors and microcontrollers and how they are different from each other. What is a Microprocessor? As its name implies, it is a processing device that converts data into information based on some sets of instructions. It is a very ...
