Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
Hello, everyone, I hope you are doing great. In this tutorial, I am going to explain you about C# checkbox control, in my previous tutorials I have already explain you, C# RadioButton Control, C# ListBox Control, C# Button Control and C# Checked ListBox Control. C Sharp checkboxes have their own values in point of sale mission and desktop application development. Checkboxes are basically used to retrieve the specific data from the user.
C# CheckBox allows the user to give specific input. It's mostly used where we have to retrieve the specific data from the user such as the gender selection, terms and condition agreement, and age-restricted data. You can simply use a single object C# CheckBox or multiple objects it totally depends on your requireme ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on DC Motor Control using myRIO. I will first provide you a bit information about DC motor then we will move forward towards DC motor control using myRIO. DC motor is an electronic instrument which is used to convert electrical energy into mechanical energy. It plays a vital role in industrial applications. It has also great importance for the engineers to to study about its working principle. DC motor has basically two input terminals. At one terminal we have to provide voltage supply and the other terminal will be attached to the ground (0V). And if we change the polarity, the direction of the motor will also be changed co ...
Hello Guys! Hope you’re well today. Happy to see you around. I welcome you on board. In this post today, I’ll detail the Introduction to 1n5822.
The 1n5822 is a Schottky diode that comes with a low forward drop voltage around 0.525V which means it needs 0.525 voltage to conduct the current in forward biased direction. It supports a load under 3A and is an ideal pick for switching applications with low current ratings. And the 40V is the maximum repetitive peak reverse voltage Vrrm of this tiny device.
Just bear with me for just 2-min as I’ll be discussing the datasheet, Pinout, specifications, and applications of this tiny little device.
Let’s get started.
Introduction to 1n5822
1n5822 is a Schottky diode, also known as a hot-carrier diode, ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to MPR121. MPR121 is a touch sensor controller, its working is like the capacitor's working principle. This module has twelve electrodes points, it communicates via I2C protocol. When any objects come closer to an electrode point, we can observe the presence of an object by variation in capacitance of an electrode. It's working voltage should be between 2.5 to 3.6 VDC.
MPR121 is used in different industrial projects and electronic devices such as mobile phone and remote control systems. In today's post, we will have a look at its working, pinout, protocol, applications, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have ...
Essay writing for the most part request that you exhibit that you have drenched yourself in the course material and that you've done some reasoning all alone; questions not treated finally in class regularly fill in as assignments. Luckily, in the event that you've invested the energy into becoming more acquainted with the material, at that point you've more likely than not started suspecting autonomously. In reacting to assignments, remember the accompanying guidance.
Beware of straying. Particularly in the draft stage, "talk" and "examination" can lead you starting with one characteristically fascinating issue then onto the next, at that point another, and after that ... You may end up following a garden of forking ways and lose your direction. ...
The electrical grid is a part of our infrastructure that we often overlook. It provides the power needed to run our homes, businesses, and critical services shaping the society we live in. Have you ever stopped to think about the history and importance of this network? Let's delve into how it functions, from the energy sources that fuel it to the technological advancements, the challenges it confronts, and what lies ahead.
The Modern Energy Grid is a Very Sturdy System
When was the time you faced a power outage? When your lights flicker, or the power goes out, it's a reminder of how we depend on the grid. Our daily routines are closely connected to its operation powering everything, from our morning coffee makers to equipment in hospitals. Disruptions in the grid can have far-reachin ...
Welcome to the next tutorial of our Raspberry Pi programming course. In our previous tutorial, we learned how to create a timelapse video with still images and understand how phototimer and FFmpeg work. In this lesson, you'll make a button-controlled "music box" that plays different sounds depending on which buttons are pressed.
What you will learn
Connect button pushes to function calls using the Python gpiozero package and uses the Python dictionary data structure
Components
Raspberry Pi
Breadboard
Buttons
Jumper wires
Speaker
Set up your project
For this project, you'll need some audio samples. On Raspbian, there are many audio files; however, playing them with Python can be challenging. You can, however, transform the audio files ...
Hello friends, hope you all are having fun and enjoying life. In today's post we are gonna see how to send data to serial port in MATLAB. Its a requested tutorial, asked by a follower and after giving him the code, I thought to share it on our blog so that others could also get benefit from it. We have discussed serial port many times and have seen how to communicate with it using different software but we haven't yet discussed how to send data to serial port in MATLAB. So, in today's post I am gonna share the complete code for sending data to serial port in MATLAB.
Serial port is most common way of communication, we can send or receive data using serial port. Normally, in engineering projects there's a need to send or receive data from microcontr ...
Hello everyone, I hope you all are doing great. Today, we are going to share the second chapter of Section-III in our Raspberry Pi programming course. The previous guide covered how to interface an LDR Sensor with Raspberry Pi 4. This tutorial will cover the basics of hooking up a soil humidity sensor to a Raspberry Pi 4 to get accurate readings. Next, we'll write a Python script to collect the data from the sensors and display it on a Serial monitor.
Are you aware that you can utilize a Raspberry Pi 4 to track the water absorbed by the soil around your houseplants or garden? This helpful guide will show you how to install a soil humidity sensor that will send you a text message when your plant needs watering. A Pi 4, a soil humidity sensor, and a few low-priced components are required. A ...
