Thank you for joining us today for our in-depth Raspberry Pi programming tutorial. The previous guide covered the steps necessary to connect a fingerprint scanner to a Raspberry Pi 4. In addition, we developed a python script to complement the sensor's ability to identify fingerprints. Yet, in this guide, we'll discover how to interface a ws2812 RGB to a Raspberry Pi 4.
Bright, colorful lights are the best, and this tutorial shows you how to set up Fully Configurable WS2812B led strips to run on a Pi 4 computer as quickly and flexibly as possible. In that manner, you can have the ambiance of your home reflect your tastes.
In most cases, when people talk about a "WS2812B Strip," they mean a long piece of extensible PCB with a bunch of different RG ...
PCB stands for printed circuit board. You will find PCBs in pretty much all electronic devices. It is usually green/blue in color. The PCB is a circuit in a board that permanently holds all the components of a circuit. It is the main part of an electronic device. This board controls and regulates the function of the whole device. A circuit may work perfectly in a breadboard. But breadboard circuits are not suitable for use. It will only be eligible to be used in a ready-made product if implemented in a PCB. This is why PCB designing should be done with utmost care.
Where to order error-free PCBs
It takes a lot of knowledge and expertise to manufacture good-quality PCBs. PCBway is a trusted PCB manufacturer. While their head office is located in China, they ship PCBs worldwide ...
Hello friends, I hope you are all fine and doing great. In today's tutorial, we will have a look at a detailed Introduction to MFRC522. MFRC522 is an RFID Embedded module used to read and write RFID cards and operates at 13.56MHz contactless communication. It is a less costly, low-voltage, and small-sized non-contact card chip. It is the best choice for intelligent instruments and portable handheld devices. It communicates with microcontrollers over SPI Protocol.
MFRC522 is used in different engineering projects, mostly for security purposes in offices, banks, plazas, etc. You must have seen in English Movies that a person just shows his ID card to the machine and its whole profile data pops up on the computer and if he is authorized then the front door automatically ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a Traffic Signal Control using Arduino. Few days earlier, I have posted the same tutorial but it was Traffic Light Signal Using 555 Timer in Proteus ISIS and today we will do the same thing but using Arduino programming. Its quite a simple but good starting project on Arduino. So, if you are new to Arduino then must give it a try.
Traffic Signal Control is quite a usual thing. We see traffic signals daily on our roads and usually engineers are asked to design such projects in their initial semesters. If we look at the traffic signals then we can see they are simply turning ON and OFF lights at some fixed regular intervals. and the pattern is quite simpl ...
Hey Fellas! We are here to help you with the latest information related to your field of interest so you keep coming back for what we have to offer. Today, I'm going to unlock the details on the Introduction to PBN and Why it Important for SEO.
This is the fourteenth article of complete SEO series. You can check my previous article on Web 2.0.
Before we move forward and check the importance of PBN in SEO, we must know what is PBN? PBN stands for private blogging network and is defined as a number of blogs you build for linking back to your main blog.
A huge round of applause is due for the SEO Gurus who still guide you through traditional techniques for SEO that have been abandoned long while ago. It is true, PBN is used for better SEO that ult ...
Hello students! Welcome to another tutorial on the integrated circuit in Proteus. Different integrated circuits are revolutionizing the electronic world and today we are discussing one of them. The core topic of this tutorial is the 74LS160 IC in the proteus but before that, we’ll understand the basics of this IC.
In this article, we’ll start learning the 74LS160 from scratch. We’ll see its introduction and datasheet in detail. You will see the truth table, logic diagram, and pinouts of this IC in detail, and then we’ll move on to the basic features of this IC. You will see the simulation of 74LS160 in Proteus and in the end, we’ll go through some important applications of this IC. Let’s move towards the introduction first.
Figure 1: Top view of 74 ...
In the introduction, I will extensively explain the property r and how to impact them are so. Let us start. Then I explain properties that are related to fluid flow.
First of all, I will start with the word Property. The definition of property is as follows:
Property
The word property is defined as any characteristic of the system. There are two main types of the property named intensive and extensive.
Example
The examples of property are as follows
Temperature -T
Pressure - P
Mass – m
Types of Properties
Following is a brief explanation of the types of properties.
Intensive Property
The intensive properties are the ones that are independent of mass, temperature, densit ...
Hi Friends! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to Arduino Beetle.
Arduino beetle is the smallest Arduino board that comes with the functionality of Arduino Leonardo. This board is a remarkable addition to the minimalistic Arduino technology. It is based on the microcontroller Atmel Atmega32u4.
With the inception of innovations in modern technology, electronic devices are becoming light, more compact that happen to perform a lot of functions. These devices are economical and require little to no prior knowledge to get your hands dirty with them.
All Arduino boards are microcontrollers but not all microcontrollers are Arduino board. While using the Arduino board, you don’t ne ...
Hello friends, I hope you all are doing well. Welcome to the 9th tutorial of our Raspberry Pi programming course. In the last chapter, we generated a PWM signal from our Raspberry Pi to control the brightness of an LED. We also studied different functions used in Python to perform PWM. In this chapter, we'll get a bit advanced with PWM and use it to control the speed and direction of a DC motor with the help of a motor driver IC.
To control the speed & direction of the DC Motor, we will:
Design a Circuit Diagram.Write Python code.
Components RequiredWe will use the following components to control the DC motor speed:
Raspberry Pi 4.DC Motor.Motor driver IC(L293D).Breadboard.
Jumper wires.
Controlling DC Motor speed wi ...
What raw materials that your PCB is comprised of?When you cannot answer this question clearly, please continue reading. When you are interested in PCB raw material testing, you better keep reading. When you are in doubt about the quality of the JLCPCB board material, you must continue reading. All corporations that value products and services paramount importance. The raw material is life for a product. This is especially true for PCB production. How JLCPCB controls the level of raw materials quality? The testing videos tell the truth.
JLCPCB never take undue advantage of Non-A grade board
