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 ...
Hello readers, I hope you are all doing great. Welcome to the 2nd lecture of Section 5(ESP32 Sensors) in the ESP32 Programming Series. In the previous tutorial, we discussed the built-in ESP32 Hall Effect Sensor. In this tutorial, we will discuss another inbuilt sensor of the ESP32 i.e. Capacitive Touch Sensor.
ESP32 Board has 10 built-in capacitive touch pins, which generate an electrical signal when someone touches these pins. These ESP32 touch pins are normally used to wake up the board from deep sleep mode. These touch pins are also used to replace the normal mechanical buttons with touch pads, improving the presentation of the IoT projects.
Here's the video demonstration of the ESP32 Capacitive Touch Sensor:
Before going forward, let's first understand how this touch sens ...
Hello readers, hope you all are doing great. Today, we will discuss interrupts and timers in ESP32 and how to handle internal as well as external interrupts. So, we will discuss What is interrupt, Polling, ESP32 interrupt, Software interrupts, Hardware Interrupts, IRS (Interrupt Service routine), Steps to execute an interrupt or how is an interrupt handled in the microcontroller, Code description for ESP32 interrupts with Arduino IDE, Code description for hardware interrupts, Why is it preferred to use timer to add delay instead of using delay() function. So, let's get started:
What is Interrupt?
Interrupts are used when a micro-controller needs to continuously monitor for an event while the same micro-controller is executing a particular task ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at the 5 Ways to Prevent Your Car from Being Stolen. Every year over 720,000 motor vehicles are stolen, according to the official site of the United States government. Thieves have gotten savvy, using technology and new methods to make stealing cars easier than ever. It is crucial to take steps to protect your vehicle from being stolen. Here are five ways to do just that:
Install a Security System
A good security system includes an alarm, immobilizer, and battery backup if you lose power to your car for any reason. It should have a remote lock/unlock capability which can be helpful if someone finds or steals your keys ...
The evolution of technology over the decades has helped almost all sectors to grow and flourish. And, the medical sector is no different. The way medicine was practiced a couple of decades ago has been completely changed today. This has obviously brought in multiple benefits to the patients. The treatment time has lowered and so has the accuracy increased. People now trust technology to get their treatments done.
This article highlights certain technologies that have transformed modern medicine.
Electronic health records
This is the prime example of how technology has transformed the way of conducting treatments and keeping records. The paper filing system of patients is now long gone. It is now replaced with electronic record-keeping. This ...
EEPROMs (Electrically Erasable Programmable Read-Only Memories) allow the non-volatile storage of application data or the storage of small amounts of data in the event of a power failure. Using external memories that allow you to add storage capacity for all those applications that require data recording. We can choose many types of memories depending on the type of interface and their capacity.
EEPROMs are generally classified and identified based on the type of serial bus they use. The first two digits of the code identify the serial bus used:
Parallel: 28 (for example 28C512) much used in the past but now too large due to having many dedicated pins for parallel transmission
Serial I2C: 24 (for example 24LC256)
Serial SPI: 25 (for example 25AA080A)
Serial - Microwire: 93 (for ...
Hello everyone. Today is a great day that we are going to put our focus on another type of PCB. So far in the previous articles, we have looked at high speed, metalcore, high density interconnect and the ceramic types of PCBs. In this article, we are going to introduce another type of PCB that might find great use in your day-to-day interaction with the printed circuit boards. it is very important for a designer to take note of how PCBs have evolved and how they have become an important aspect in the design of successful electronic devices. It has become hardly difficult to come across any time of an electronic device that does not involve the use of printed circuit boards.
In PCB boards you come across LEDs fixed in them, and due to the evolving w ...
Hello friends, I hope you’re all well and healthy. In today’s tutorial, we will be going through a simple, yet effective practice to design a 4-way traffic light simulation in Proteus software. This project is designed for undergrad engineering students with majors in electronics, electrical and mechatronics engineering. It is also useful for people that want to learn the basics of circuit design and Arduino programming.
4-Way Traffic Light Control using Arduino:
Traffic lights are an integral part of the world’s transportation systems. Over the years a number of different algorithms regarding traffic lights have been developed. The algorithm being used at any place for the purpose of controlling traffic takes into account of various factors, such ...
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 ...
The SPI (Serial Peripheral Interface) protocol, or rather the SPI interface, was originally devised by Motorola (now Freescale) to support their microprocessors and microcontrollers. Unlike the I2C standard designed by Philips, the SPI interface has never been standardized; nevertheless, it has become a de-facto standard. National Semiconductor has developed a variant of the SPI under the name Microwire bus. The lack of official rules has led to the addition of many features and options that must be appropriately selected and set in order to allow proper communication between the various interconnected devices. The SPI interface describes a single Master single Slave communication and is of the synchronous and full-duplex type. The clock is transmitted with a dedicated line (not necessari ...
