Greetings and welcome to today’s lecture. It's our 7th tutorial in the PCB learning series. In our previous lectures, we have studied the two main types of PCB i.e. Single-sided and Double-sided PCB. Today is going to be a very interesting and interactive class about Through Hole Technology(THT), which is applied in the process of designing printed circuit boards.A PCB board has a properly designed circuit on it and it's composed of connecting traces/paths and various electronic components. The electronic components are mounted on the board in two different ways i.e. Through-hole and Surface-mount. We will cover Surface-mount in our next lecture and today, we will discuss how to mount components on PCB boards using though-hole technology.So, let's ...
Hello readers, hope you all are doing great. In this tutorial, we are going to discuss a mechanism that allows users to update the ESP32 with a new program wirelessly or over the air (without using a USB cable to upload a new program).
Over-The-Air (OTA) programming
Fig. 1 ESP32 OTA
OTA programming is the mean by which a product manufacturer or product service provider can update the features or functionality of the device wirelessly or over the air, after the device has been deployed in the field where connecting a cable or uploading the code serially is difficult.
One key advantage of OTA is that a single central node can send an update to multiple ESPs on the same network.
The device must have a provisioning client capable of receivin ...
Hello everyone, Welcome to our new project. Our new project plays a very important role in our daily life as it is directly connected to our lives. In this project, we are going to design an Accident Detection module. Accidents are the most common thing we hear about in the news, and in social media. Everyone here or there has seen accidents or has been with one. So when any such incidents happen, we inform respective stations or hospitals in that emergency situation. But what about the accidents that happen at night, or in places where there is very less crowd or you are alone. So, to address this issue and provide a potential solution for that, we are going to learn how to detect an accident automatically and inform nearby aid/help stations.
We ...
A Digital to Analog Converter(DAC) performs the task of converting digital words of n bits into voltages whose amplitude will be proportional to the value of the code expressed by the words themselves. Since the input binary words represent a succession of finite codes, the voltage coming out of a DAC cannot be continuous over time but is made up of as many levels as the converted codes are. This means that the devices to which the analog signal produced by a DAC is sent must filter it with a low-pass characteristic (integrating action). The operating criterion of a DAC is simple: in fact, it is sufficient to have a succession of as many voltages as there are convertible codes, obtained for example by means of a weighted resistance network (i.e. t ...
IoT – the Internet of Things – has revolutionized the way we use and perceive technology over the last couple of decades. From introducing the world to smart homes and cars to envisioning a more efficient office and work environment, IoT has done it all.
We have integrated IoT in our industrial, tech, and agricultural sectors, as well as our personal lives. However, one of the most fascinating ways IoT has influenced our current society is through its contribution to the health and medical sector.
The healthcare sector managed to get the most out of the Internet of Things technology. Utilizing modern sensors to keep a close eye on their patients’ conditions, these IoT systems are making life easier for medical professionals. And while IoT systems ...
