Arduino Image processing CCTV camera system application designing and programming
Description: Arduino Image processing –In this tutorial you will learn how to use image processing, Arduino Uno and PIR sensor to create your own Arduino based CCTV camera device. “Visual Basic” will be used to create the image processing program in this tutorial vb.net.This application works in conjunction with the Arduino Uno connected PIR sensor. Once both the PIR sensor and the image processing application detect the human, a picture is automatically captured and stored in a folder. Visual Basic.net will be used for the image processing software. It’s really easy to model image processing applications in vb.net. The Frontal face XML archive is used in this application for human identification.Once the computer application detects the human face and also receives a signal from the Arduino, a picture will be taken automatically and stored in the desired folder. The Amazon Purchase links are given below: Pir motion sensor:…

Arduino Mega HMI touch screen calibration and programming
Description: In this project, we will learn how to use the TFT LCD Touch Screen to create an Arduino or Mega based HMI system. This is a very basic tutorial in which we will control a led and display in seconds the On Controller Time. While I’m using this HMI touch screen in my upcoming tutorials To view data from sensors on this screen To make a real-time map tracking system, I will integrate this with the Neo 6 M GPS unit. To manage multiple loads I’m also going to use this RFID touch screen to display images. We will use this with the fingerprint module to create a voting system for our upcoming tutorial. And so on and so forth. In so many other things I’m going to use this touch screen. So sign up for my website and YouTube channel right now, so you’ll never miss any of my upcoming tutorials. Nowadays, the HMI Touch screens are most commonly used in the control and monitoring industries. This removes the need to change hardware. In addition, it’s easy to use the HMI touch screen. It is possible to add new functions, the interface configuration can be changed at any time. Specific pages can be configured for electrical device or sensor control and monitoring. The HMI touch screens are used with PLC ‘S in Industries and such HMIC touch screens are expensive. The aim of this tutorial is to support you guys, how you can use a 5-inch TFT touch screen to build …

Request Temperature Data Using GSM and Arduino programming
Description: This tutorial is based on monitoring temperature and humidity using a cell phone, Arduino and the well-known temperature and humidity sensor DHT11. In this project, we will learn how to use your cell phone to measure temperature and humidity from anywhere in the world. There are projects where the data from the Sensors is sent after regular intervals, which I don’t think is good. This project differs from the rest of the GSM-based projects, as the temperature and humidity values are only sent in this project when the owner sends a request message. The Amazon Purchase links are given below: dht11 sensor: https://amzn.to/2sPejzO GSM…
