Welcome back to another Python tutorial for the Raspberry Pi 4! The previous tutorial showed us how to construct a Raspberry Pi-powered cell phone with a microphone and speaker for making and receiving calls and reading text messages (SMS). To make our Raspberry Pi 4 into a fully functional smartphone, we built software in Python. As we monitored text and phone calls being sent and received between the raspberry pi and our mobile phone, we experienced no technical difficulties. But in this tutorial, you'll learn how to hook up the PCF8591 ADC/DAC module to a Raspberry Pi 4.
Since most sensors only output their data in analog values, converting them to binary values that a microcontroller can understand is a crucial part of any integrated electroni ...
Marketing is the cornerstone of any business. Yet, so many business owners struggle to find new and innovative ways to promote their business to potential consumers. In an ever-evolving economy, marketing your endeavor is going to involve plenty of thinking outside the box. We no longer live in a world were a simple ad-campaign or coupon promotion is enough to drive eyeballs to a site or feet through the door. If you’ve been looking for new ways to market your business without breaking the bank, there is one new method you should try: text to speech technology. Not only is it one of the freshest ways to market your business, but it is one of the most affordable. Let’s take a look at how text to speech technology can be used to market your business. ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a new exciting post on Send SMS with SIM900D in Proteus ISIS. In my previous post, I have shared the new GSM Library for Proteus, which is the first ever designed library for Proteus, and I am quite excited while sharing its features. So, today, we will use this GSM Lirbary for Proteus and we are gonna send sms with Sim900D module available in that library. We are gonna design this whole project in Proteus ISIS.
If you wanna implement it on hardware then you must have a look at Send SMS with SIM900D module with Arduino which is designed in real hardware but today we are gonna just do the simulation part. Iam not gonna use any Microcontroller today. Inst ...
Hello everyone, I hope you all are doing great. Today, I am going to share a new tutorial in which we will have a look at How to Earn with Primedice. If you remember the Tutorial1: Earn with Freebitco.in in which I have shared how to earn with freebitco site and earn bitcoins. Today, I am gonna share a new bitcoin site and I must say that Primedice is quite better then Freebitco. I will share why its better then the previous one in detail.
AS I have discussed this in my previous tutorial that Engineers normally don't do well when it comes to earning so they must find some way through which they can earn some money. And online earning is the best way to earn money. In online earning, bitcoins are really very precious because if you have a look at i ...
Hi learners! Welcome to the next episode of learning the arrays using string data. We have been working with the arrays and in the previous lecture, we saw the interesting characteristics of the string arrays. In the present lecture, our target is to get knowledge about the built-in functions and we will take the strings in the array so that we may know about both of them together. String arrays are used in many officials uses and therefore, we want to use the built-in functions that every Python programmer must know. Here is the list of the concepts that will be polished in this lecture:
What are the built-in methods?
How do you differentiate between methods and functions in programming?
Give different examples to understand different built-in methods to be used in the same code.
How ...
Hello folks, I hope you are having a great day. Today, I am going to start this new tutorial series on JavaScript and here's our 1st tutorial titled Introduction to JavaScript. This is a beginner level tutorial series, where we will start from very basics & will slowly move towards complex concepts. If you're not a beginner or looking for secure development training or advanced tutorials, stay tuned, more training is coming.
We can use any development Editor for running JavaScript and for this tutorial series, I will use Microsoft Visual Studio Code, which is free to use & you can download it from official site. You don't need to be an expert programmer, in order to learn JavaScript, but you must have some basic knowledge of HTML & CSS ...
Hello, readers. Welcome to the MATLAB tutorial, where you are learning the basics to advance information about MATLAB without discussing unnecessary concepts. In the last lecture, there was a discussion about variables and their declaration, usage, and types in detail using the MATLAB command prompt. This time, you are learning the workspace window of MATLAB. Usually, people while learning ignores this window because they do not bother about what is happening in it, but the experts know that by applying the simple rules in the workspace window, they can easily get better results. At the end of this lecture, you will be able to answer the following questions:
What is the workspace window of MATLAB?
How can you save the files from the workshop in different ways?
What is the method to load ...
Hello friends, I hope you all are doing well. In today's tutorial, I am going to share a new Proteus Library of ESP32 embedded module. ESP32 is a microcontroller board used mostly in IoT projects. It's a successor of ESP8266 or NodeMCU. We have already shared the NodeMCU Library for Proteus and I hope you guys have enjoyed it.Proteus software is not capable of handling WiFi or BLE technology, thus we can't implement these technologies in the ESP32 board. Though, you can use its input/output pins to interface embedded sensors and modules. You can also use it to design the Circuit Diagram of your Project.So, let's have a look at How to simulate ESP32 board in Proteus:
ESP32 Library for Proteus
First of all, download the zip file of Proteus Library for ESP32 board, by clicking the below b ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to Create Promotional Videos Like a Pro. Creating a promotional video is one of the major factors for dominating online traffic. It is the most powerful part of your content. According to a prediction, in the next few years, most of the part on the World Wide Web will be taken over by the videos. Cisco estimates that video traffic will contribute 82% of the global internet traffic by 2021. Undoubtedly, this number is only going to rise up. It is because videos are capturing and keeping the attention of people more than text-based content.
If you are seeking to create a promotional video for your business like a pro and don’t know from where to start, sta ...
Hi Guys! Happy to see you here. Thank you for viewing this read. In this post today, I’ll walk you through the complete Introduction to BC550. BC550 is a low-power low-frequency general-purpose bipolar transistor. It is mainly used to drive loads under 100mA. BC550 carries three terminals where a small current across one terminal is used to control the large current across the remaining terminals. It’s primarily used for amplification and switching purposes. Transistors are critical components and building blocks of modern electronic circuits. Bipolar junction transistors are divided into two main types named NPN transistors and PNP transistors. The BC550 falls under the category of NPN transistors and is available in a plastic TO-92 case. I sugge ...
