Hello friends, I hope you all are doing great. Welcome to the 3rd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. We have already discussed the two built-in ESP32 sensors i.e. Hall Effect Sensor and Capacitive Touch Sensor. Today, we are going to discuss the 3rd and final built-in ESP32 sensor i.e. Internal Temperature Sensor.
ESP32 Internal Temperature Sensor is used to calculate the temperature of the ESP32 core. So, we can't use it to measure the ambient temperature (the temperature of the atmosphere), for that, we need to use embedded temperature sensors i.e. DS18B2 ...
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.

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?

Hi friends! I hope you are doing well! Today we are going to learn and practice a new topic which is a very crucial technique in plc programming. the topic is called “latching”. We mean by Latching to keep the output running starting from the instance of giving a kick-off command until we hit a command to stop running of the motor. Imagine my friends, operator wants to start a motor by hitting a start push button and want the motor to keep running and leave and go for doing another task or job. And then it keeps running until the operator wants to stop it. The problem here is that, once the o ...
Over the past century, dental care has remained a relatively rigid area of healthcare. However, the accelerated digitization of the past two decades has seen the sector rapidly adopt mainstream technologies, with the advancement taking a seemingly steeper trajectory by the day. We looked at some of the new technologies making their way into dentistry and came up with this list of what we reckon will rock the world of dental care for years to come:

Hi friends, how are you doing? Today will integrate all of what we have learned so far in this series to build the first project based on ladder logic programming. Because we all are interested in industry, we pick one industrial project, Bottle Filling and Capping Projects, which is very common today. The problem we are going to solve today is bottle filling and capping. We have learned all basics of ladder logic including contacts and coils operation, logic gates, rising and falling edges, timers, and counters. So, today we will utilize all of these components to implement a complete ladder ...
