Hi friends, today we are going to learn a good technique to run multi outputs in sequence. In another word, when we have some output that is repeatedly run in sequence. In the normal or conventional technique of programming we deal with them individually or one by one which takes more effort in programming and much space of memory. So instead we can use a new technique to trigger these outputs in sequence using one instruction which will save the effort of programming and space of memory. In this article, we are going to introduce how to implement sequencer output instruction. And practice som ...
Hello friends, after completing that basic part of ladder logic programming, let us today go through one topic which is not essential to know to complete a PLC ladder program but it is important t have our code readable program and reusable pieces of code. That could happen by using what so-called a subroutine. So what is a subroutine? Well, it is a piece of code that includes a few rungs to perform specific tasks. that piece of code can be reused numerous times through the program when we need to call it for performing that task. That subroutine enables us to structure our code like building ...

Hello friends, I hope you are doing very well. Today we are going to learn and practice the master control reset (MCR)! So what is that MCR? Well! This is a tool you might use to control a group of devices with one push button for performing fast emergency responses with one click for a group of devices in one zone. In another word, you divide the program into zones and put this zone between a master control to control their operation as one unit by one contact. This technique is useful for applying emergence stops and also protecting some equipment by applying a safety restrict ...
Hi friends, I hope you are very well; today in this tutorial, we will practice conditional jumping for performing some code at the occurrence of some conditions. Like any other programming language, jumping is one of the most common approaches to transfer the execution from its sequential mode to run different processes or instructions marked by a label and bypassing the lines of codes in between the last executed transaction before the jump instruction and the labeled instruction whom the program is going to move to. The good thing about this technique is shortening the scan cycle of the pro ...
Hi friends and hope you are doing very well. Today we would like to take one tutorial which is very essential in the industry which is analog input processing for handling analog measurements of physical signals like temperature, humidity, pressure, distance, flow and level of liquids, etc. Typically, sensors produce two types of analog signals to represent the equivalent measured signal which is current and voltage signals. The currently produced signals would be within the range of 4-20 mAwhile voltage signals are in the range of 0-10 v. because, that output signals represent physical signa ...
Hello friends, I hope you all are doing well. Welcome to the 11th tutorial of our Raspberry Pi programming course. In the previous chapter, we have seen how to regulate the speed of a Stepper motor with Raspberry Pi 4. Today, we'll work on the servo motor and will control it with RPi4. So, let's get started:
Components Required:We will need the following components to control Servo Motor with Raspberry Pi 4:
Raspberry Pi 4.
Servo Motor.
Male-to-female jumper wires.
What is a servo motor?
A Servo Motor is a simple DC motor with a position feedback Control System and a gearbo ...
