They often include essential instructions. Sometimes starter kits come with educational resources. Their purpose is to make learning quick and easy. For DIY projects, a starter kit serves as a convenient entry point. They offer the necessary foundation and guidance to explore and engage in a new interest. Why we need starter kits: Starter kits make learning easy. Beginners cannot make a good parts list for learning. They ...
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 techn ...
Hello readers, I hope you all are doing great. In our previous tutorials on raspberry pi Pico, we discussed the basic features, architecture, download and installation of development environments for raspberry Pi Pico programming. In this tutorial, we will learn how to access and control Raspberry Pi Pico and its GPIO pins to implement LED blinking using MicroPython. Introduction Raspberry Pi development boards are quite popular and frequently used among students and hobbyists. But the drawback of Raspberry Pi is their cost i.e., around $35-$45. So when cost of the development board is of prime importance the users prefer to use ESP8266, ESP32, Arduino, PIC etc. over Raspberry Pi. To overcome this drawback, Raspberry Pi foundations designed a new board i.e., Raspberry Pi Pico which is a co ...
Internet of Things is a system of multiple inter-related computing devices. The factor ‘thing’ in IoT is designated to an entity capable of communicating data over a network (IOT), which can be a digital machine, sensor, human being, animals etc. Each component that is included in IoT network is assigned with an unique identity called UID and the ability to communicate data over IoT network without any external human or computer intervention. Hello readers, I hope you all are doing great. In our previous tutorial, we discussed how to upload data to Firebase Real-time Database using ESP32. In this tutorial, we will learn how to read the data stored on the Firebase Database with ESP32. We can access the data stored in Firebase database from anywhere in the world, which makes this preferable ...
The IoT is the interconnection of physical objects or devices with sensors and software accessing capabilities to communicate data or information over the internet. To build an IoT network, we need an interface medium that can fetch, control, and communicate data between sender and receiver electronics devices or servers. Espressif Systems created the ESP32 Wi-Fi chip series. The ESP32 module is equipped with a 32-bit Tensilica microcontroller, 2.4GHz Wi-Fi connectivity, an antenna, memory, and power management modules, and much more. All of these built-in features of this ESP32 module make it ideal for IoT applications. Hello readers, I hope you all are doing great. In this tutorial, we will learn another application of ESP32 in the field of IoT (Internet of Things). We are using a PIR se ...
Greetings! I sincerely hope everything is going well for you all. In this course, we are going to learn step-by-step how to program in Python. The course covers all you need to know about the Python language, from installation to advanced topics. In addition, we'll talk about Python career jobs and do a few projects to strengthen your skills. According to my research, Python is among the top programming languages in use today. (I mean, no offense). Since I am also a Python programmer, I may sound a little prejudiced, but I can certainly declare that I am a huge fan of the language. This tutorial series is meant for absolute beginners with no prior knowledge of python programming, it is also of great help for experienced python programmers looking to brush up on their knowledge. Anyway, let ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn about the ESP-NOW protocol and how to communicate data between two ESP modules through ESP-NOW protocol and that is too without Wi-Fi connectivity. What is ESP-NOW Protocol? Fig. 1: ESP-NOW Protocol ESP–NOW is a connectionless communication protocol that is used for sharing small data packets between two ESP boards. This protocol is developed by Espressif. Features of ESP-NOW Protocol: It is a low-power wireless protocol, which makes two or more ESP devices communicate directly with each other without using Wi-Fi. ESP-NOW protocol does not require a handshake for establishing a connection but, they require pairing and once the devices are paired they can exchange data. ESP-NOW offers a persistent connection betw ...
Hello readers, I hope you all are doing great. In our previous tutorial, we learned SMTP server and how to implement an SMTP server for sending emails with ESP32 . In the previous tutorial, we also demonstrated some examples like sharing raw text, HTML text, images and text files. So, at the transmitter end, we are using the SMTP server. But, what about the receiver end? At the receiver end, we use another protocol called IMAP (or Internet Message Access Protocol) and POP3 (Post office Protocol V3) for receiving the emails. Fig. IMAP and SMTP What is IMAP Protocol and How does it Work? IMAP is an application layer (TCP/IP) protocol that is used at the receiver end to receive emails from SMTP server or mail server. IMAP follows the client/server model. Fig. IMAP Protocol Features of IMAP pr ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send an email using ESP32 module. We will also learn to send text files, images or some sensor readings using the SMTP server using the ESP32 module. In IoT (Internet of things), there are various applications where we need to send emails carrying information like sending some sensor readings, altering emails, images, text files and much more. What is SMTP? SMTP or simple mail transfer protocol is an internet standard for sending and receiving electronic mail (or email) where an SMTP server receives emails from the email client. SMTP is also used for setting communication between servers. Various email providers like Gmail, Hotmail, Yahoo, etc. have unique SMTP addresses and port numbers. How does SMTP wo ...
