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 gearbox.A Servo Motor's primary advantage is its ability to maintain its shaft's angular position at any desired angle i.e. if we want to keep our shaft at 67 degre ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial looked at how to Interface DS18B20 with Raspberry Pi 4. This tutorial will teach us how to create a time-lapse video with still images and understand how phototimer and FFmpeg work.
What is time-lapse?
When photographing something over a lengthy period, "time-lapse" comes to mind. A video can be created by mixing the still photos. Plant development may be tracked with time-lapse movies, as can the changing of the seasons. They can also be utilized as low-resolution security cameras.
Components
Raspberry pi 4B
Pi camera
Connect to the Raspberry Pi
Cameras that can be used with the Raspberry Pi are a bit limi ...
Welcome to the next tutorial of our raspberry pi 4 programming course. A previous article covered connecting a Remote Control Radio Frequency Module (433 MHz) to a Raspberry Pi 4. To turn things on and off wirelessly, we programmed a Raspberry Pi 4 to act as a radio-frequency (RF) remote control. However, this guide will study how to wirelessly pair a Raspberry Pi 4 and an ESP32. After reading this article, you'll get a good grounding in the fundamentals of Bluetooth module operation between two ESP32 and Pi 4 communication.
When it comes to sharing data over short distances using Ultra High-Frequency Radio Waves, Bluetooth is one of the most reliable and effective short-range wireless communication solutions. Since Bluetooth Technology was initially conceived as a cable substitution tech ...
Hello people! Welcome to an exciting series on The Engineering Projects in which we are studying MATLAB. This series is not just organized just for technical people but for anyone with a basic knowledge of programming and mathematics. We will define each and every concept from scratch and you are not going to bore in any lesson because you will learn new and exciting things in every lecture. If you are wondering what MATLAB can do and what some of its features make it the best calculator and it performs complex calculations in just seconds. You will also see some other parts of MATLAB that make it the best. Have a look at the list of the topics that we are going to discuss with you:
What is MATLAB?
What are some basic features of MATLAB?
If I need to have some prerequisites in MATLAB?

Key TakeawaysStreaming data integration is becoming essential for Snowflake use cases that depend on current operational data.The strongest platforms support reliable change capture, low latency, schema evolution, backfills, delete handling, and efficient warehouse writes.Database replication, event streaming, SaaS ingestion, and pipeline orchestration are different integration patterns and should be evaluated separately.A good platform should reduce source database impact while keeping Snowflake tables trustworthy and up to date.Data teams should define latency, volume, ownership, transformation, and governance requirements before selecting a platform.The best choice is the platform that matches the workload, not the one with the longest connector list or the most impressive demo.Snowflak ...
Hello everyone, I hope you are having a good day. In today's tutorial, I am going to tell you about "Variables in JavaScript".
The topic, I am going to highlight today, is how to declare variables in JavaScript and types of Variable? JavaScript has variables too as many other programming languages, so let's get started with it:
What are Variables In JavaScript
Variable means anything that can vary(change). In JavaScript, Variable holds the data value, in simple words, JavaScript variables are containers and can store the data value. Variable in JavaScript are declared with var (reserved keyword).
It is the basic unit for holding or storing the data.
A variable value can change at any time.
Variable must have a unique name.
Syntax
var (Vari ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at 10 Engineering Writing Prompts Mastering the Written Form of Communication. Get surprised that engineers should be effective in writing as most humanities-minded people do? Yes, there is a problem among most specialists, who have technical knowledge. They can’t share their knowledge in a way that’s easy to understand for the audience that has no bearing on the subject. So any written paper should be clear, concise and coherent. As the world of engineering is expanding dramatically today, engineers need to develop new strategies for presenting the research ideas and results to the non-engineering audience. So how to do it effectively? You can use a lot of ...
Welcome to the next tutorial in our Raspberry Pi 4 programming course. In the previous tutorial, we learned how to automate your home with a Raspberry Pi and Bluetooth Low Energy. We found that using a Raspberry Pi 4 and Bluetooth Low Energy (BLE), users may command their household appliances from their smartphone or a web interface, and the Pi 4 will carry out the commands. This allows for a versatile and adaptable method of managing lights, thermostats, and smart plugs.
However, this Internet of Things (IoT) project aims to create a real-time Raspberry Pi weather station that displays the current humidity, temperature, and pressure values via an LCD and an online server. With this arrangement, you can track the local climate from any location in the globe over the internet and see what ...
Hello Friends! Hope you are doing well. I am back to give you a daily dose of valuable information. Today, I'll discuss the detailed Introduction to RS 232 which is a standard communication protocol mainly used for serial communication between two devices. It was first introduced by the EIA (Electronic Industries Association) in 1960 to provide a pathway for connecting one device with other peripheral devices for flawless digital communication.
It is true, that the inception of USB has grossly reduced the need for RS232 protocol, still, we can't brush off its significant importance in some industrial applications where Programmable Logic Controllers and Computerized Numerical Control Equipment are specifically programmed using RS 232 connectors ...
Hi learner! I hope you are doing great. Today, I am sharing version 3.0 of the PIR sensor library for Proteus. We have already shared V1.0 and V2.0 of the PIR Sensor Library. PIR Sensor V1.0 Library for Proteus adds a digital PIR Sensor in Proteus, while the PIR Sensor V2.0 Library adds an analog PIR Sensor to simulate. These libraries were loved by the users and this motivated us to work more on it. PIR V3.0 is analog in nature, has an error-free structure and the Pinout structure is better organized. Moreover, the design is improved a little bit and we have omitted the website link from the sensor to make it look professional.
Same as the previous version, this PIR has four pins and the details of each of them will be discussed in detail later. Therefore, don’t worry if you have no expe ...
