Hello readers, I hope you all are doing great. In this tutorial, we will learn how to access Firebase (a real-time database) to store and read values or data with ESP32.
It is Google’s mobile application development platform that can be used to can access, monitor and control ESP32 from anywhere in the world with its (firebase) real-time database.
What is Firebase?
Firebase real-time database is a development platform provided by Google which included multiple services to manage and authenticate data.
Firebase is basically a mobile and web app development platform I as works great with Android APIs) that includes features like firebase cloud, real-time data and Firebase authentication etc.
As per Firebase’s official documentation (https://firebase.google.com/docs/database), whenever a us ...
Hello everyone, I hope you all are fine and having fun. In today's tutorial, I am going to show you How to write Arduino code. In the previous tutorial, we have seen the Simple Arduino LED Example so if you haven't read that tutorial then I must suggest you to read it first because I am gonna use the same simulation with some advancements in it.
Moreover, you should also have a look at How to do Arduino Serial Communication because we are also gonna use Serial Port in today's tutorial and one more tutorial which you must read is How to use digitalRead in Arduino because we are dealing with digital pins here. So, I hope that you have read those tutorial and are ready to learn How to write Arduino code. So, let's have a look at How to write Arduino ...
Hello, fellows, I hope you all are doing great. In today’s tutorial, we will discuss the Best Search Engines Going Forward. The dominant search engine on the web for the first fifth of the 21st century had a nice run, but it can't last forever. While this has been happening, a new generation of web users has become aware that Internet trends have stagnated. After all these years of websites carefully toeing the line to avoid offending the dominant search engine, the web has become homogenized.
There are new vistas in web search engines out there. The way we do it now is by far not the only way, and search engine technology is most definitely not a closed field. At the same time, the next-generation web market is starting to take exception to be sp ...
Hi Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll detail how to prevent data loss risk in raid-based storage.
RAID (Redundant Array of Independent Disks) is a data storage virtualization technology used for data redundancy and performance improvement in an Operating System. It has redefined how storage systems store and retrieve data, and its architecture comprises multiple physical disk drive components distributed over one or more logical units.
Prevent Data Loss Risk In Raid-Based Storage
RAID levels vary from RAID 0 to RAID 51 (and beyond). Different levels have different types of redundancy offered; however, a compromise has to be made when it comes to fault tolerance and performance. Although different RAID ...
Hello friends, hope you all are fine and having fun with your life. Today's post, as the name suggests is about How to Display Serial Data on Real Time Graph in Labview. In our previous post, we have seen that how to Get Continuous Data From COM Port in Labview. Today's post is a sequel of this previous post so I would recommend that if you haven't had a look on that post then first visit it as I am gonna start today's post from where I stopped the previous one.
In the last post, we were able to get the continuous data from COM port using Labview and we have also separated the data based on a character which I have used this one "," i.e. comma. Now, suppose you are sending 3 values from your COM port and these are the sensors' values so tthe best ...
Hi readers! Hopefully, you are having a great day and exploring something new and advanced. In the competition to miniaturize electronics and increase performance, the smallest holes in your PCB, micro vias, are carrying the biggest load. Today, the topic of our discourse is micro via technology and its use for miniaturization in modern PCBs.
In this electronic revolution, the thirst for miniaturization, speed, and power will remain insatiable. Today's electronics scale down, complexity increases daily, from smartphones to wearable devices, from aerospace equipment to medical implants. Behind this miniaturization process is a key breakthrough in printed circuit board (PCB) technology, Microvia Technology.
Microvias are extremely small vias, usually under 150 microns in diameter, for ...
Hi Mentees! we hope you are doing great. Welcome to a super easy yet useful project based upon the simulation in Proteus. We are working on the Traffic Lights project that will work with the help of D Flip Flop. In this simple tutorial, you will be aware of the following concepts:
What are the Traffic Lights using D Flip Flop?
What is the role of D Flip Flop?
How does the circuit of D Flip Flop work in the Traffic Lights?
How can you simulate the circuit of Traffic Lights with D Flip Flop in Proteus?
In addition, you will find some important information about the Traffic Lights circuit in the DID YOU KNOW Sections. Let's start learning.
Traffic Lights with D Flip Flop
Who is not aware of the traffic lights? we all observe and use the Traf ...
Hey Guys! I am back to give you a daily dose of information so you can excel and grow in your relevant field and keep coming back for what we have to offer. If you are a hobbyist or student, you require a transistor for the execution of your project every now and then.
Today, I am going to unlock the details on the Introduction to 2n4123. It is an NPN (negative-positive-negative) general purpose transistor which is mainly used for the amplification and switching purpose where collector current around 100mA is required. It is a semiconductor device mainly composed of silicon and comes with three terminals where a voltage applied to the one pair of terminals is used to control the current at the other pair of terminals.
I'll break down each and ev ...
Hello everyone, and welcome back with a new tutorial in our ladder logic programming. Today we will continue the bottle line production line using ladder logic programming. Let me remind you, everyone; we have seen how to utilize the bit shift left instruction BSL to save the data that describes the state of a bottle, including the present state, size state, either large or small size and the excellent and broken state as well. And also we utilized these states to energize the large bottle and scrap solenoid to divert the bottles to the appropriate position and conveyor. At the end of the day, we have separated small, large, and scrap bottles. Today we are going to manage the scraping of the broken bottle.
Bottle line Scraping management
In each bottle line process, we have a common and ...
Hello learners! Welcome to the next episode of the arrays, in which we are moving towards the details of the arrays at an advanced level. In the previous lecture, we covered the introductions and fundamentals of arrays, dimensional arrays, and array operations. One must know that the working of the arrays does not end with simple operations, and there is a lot to learn about them. Arrays and their types are important topics in programming, and if we talk about Python, the working and concepts of the array in Python are relatively simple and more effective. The details of the advanced types of arrays will prove this statement. We have a lot of data to share with you, and for this reason, we have arranged this lecture. It is important to understand the reasons behind the reading of this lect ...
