Overview Agriculture is the backbone of the economy and is the fundamental method of occupation. The world’s large population depends on agriculture to live daily life. About 70% of The Indian population depends on the crop and furthermore, many of the crops are contributed from here. Most of the crop cannot be productive just by…
Overview This tutorial will help you connect App Inventor with a temperature sensor on an Arduino controller. Block Diagram: Pins connection: About Bluetooth module HC-05: HC-05 is a Bluetooth module which is designed for wireless communication. It uses serial communication to communicate with devices. HC-05 has a red LED which indicates connection status, whether the Bluetooth…
Introduction The ADC module is a successive approximation (SAR) style ADC with a selectable resolution of either 16 bits or 12 bits. The ADC is composed of a core and a wrapper. The core is composed of the analogue circuits which include the channel select MUX, the sample-and-hold (S/H) circuit, the successive approximation circuits, voltage…
Overview In this tutorial, we will learn how to program the ESP8266 OTA using the Arduino IDE. We will learn about an interesting feature of the ESP8266 NodeMCU module that will allow us to perform OTA updates over the air. This means that the ESP8266 module, like other Wi-Fi-enabled microcontrollers, supports over-the-air updating of firmware…
What is an Image??? Image is the combination of pixels and Pixel is nothing but a part of Picture. An image is nothing more than a two dimensional signal. It is defined by the mathematical function f(x, y) where x and y are the two co-ordinates horizontally and vertically. The value of f(x, y) at…
Overview In the modern world, water scarcity is a severe threat that requires careful consideration. In order to meet the rising demand for water caused by a rise in population, wastewater must be treated and used appropriately. Making the wastewater treatment process effective and affordable is also essential. This article suggests a method that can…
Overview In this tutorial, we will see how to use IWDG (Independent Monitor) and WWDG (Window Monitor) in STM32. Both monitors are used for a similar purpose, but the difference is in their implementation. The main difference between the two is that a standalone watcher can be reset at any time before it times out,…
GSM Network time synchronization for RTC using AT+CLTS command Since I started designing the VALTRACK GPS trackers, I have always had trouble maintaining the tracking device’s correct time because once I removed the battery, the PIC RTC lost its synchronization. I didn’t have the space or luxury to maintain a separate backup battery for the…
Overview This is a series of robots that uses three wheels to drive over almost any terrain. Works on any interior and exterior surface. This robot uses Android technology. This can be moved back and forth using 60RPM geared motors. Also, this robot can make sharp turns to the left and right. This project uses…
Overview Step 1: You must first download and install the Arduino IDE, which you can download from https://www.arduino.cc/en/Main/Software for free. If you have already installed the Arduino IDE on your computer, make sure it is the latest version of the IDE because the older version does not include the ESP32 board. Step 2 – After…
