<h2> About Arduino IDE </h2>
<p> The Arduino Integrated Development Environment - or Arduino Software (IDE) - contains a text editor for writing code, a message area, a text console, a toolbar with buttons for common functions, and a series of menus. It connects to the Arduino hardware to upload programs and communicate with them. </p>

<h2> Board Port Selection</h2>
<p> This is one of the major steps while working with Arduino IDE, as Arduino has different types of boards and supports other types of boards. So, In order to work with them efficiently, we must aware of Arduino IDE with our board and the port from which we will transfer the code to the microcontroller.</p>

<h2> Program Uploading </h2>
<p> 1) Compile the code: - After writing the code we need to compile that code for checking errors in it, this process can help us to evaluate and remove errors in our code before uploading it into the microcontroller.</p>

<p> 2) Upload the code: - After successful code compilation we must connect our microcontroller to one of the ports of our local server.</p>
<imgsrc="../images/upload.png"alt="Description of image"width="800"/><!-- Insert your image here -->
<p> 3) Monitor the output: - Arduino IDE supports a monitoring function where we can view and monitor the output achieved by sensors and microcontrollers.</p>

<h1> Embedded Programming </h1>
<h2> LED Blinking Using ESP32 </h2>
<p> ESP32 has a built-in LED on pin no. 2, I have programmed ESP32 to blink its LED at a certain time internally using Void setup, Void Loop, and delay functions. I have also used small LEDs instead of built-in LEDs.</p>
<h3> Equipment used</h3>
<p>ESP32, Breadboard, LED, Data Transfer cable, etc.</p>
<h3> Methodology </h3>
<p> 1) Arduino IDE has an inbuilt program as an example, I modified that program by changing input & output pin locations. </p>
<p> 2) I also modified the delay time for LED high and low.</p>
<p> 3) ESP32 has Built-in LED located at pin no. </p>
<p> 4) Connected ESP32 to my local computer.</p>
<p> 5) Selected appropriate board and port locations. </p>
<p> 6) Uploaded Program to ESP32 by compiling it.</p>

<h2> Distance measurement using Ultrasonic sensor </h2>
<p> The ultrasonic sensor generates ultrasonic pulses to calculate the distance or the depth of an object, here I have tried to calculate the depth of a respective object and show its exact distance using an ESP32 microcontroller.</p>
<h3> Equipment used</h3>
<p>ESP32, breadboard, Ultrasonic sensors, jumper cable & Micro USb Cable.</p>
<h3> Methodology </h3>
<p> 1) i Got a code for calculating distance using ultrasonic sensor and ESP32 from Random nerd Tutorials. </p>
<p> 2) I Modified that program by changing i/o pin location.</p>
<p> 3) Prepared ESp32 & Ultrasonic sensor and arrange then according to proram.</p>
<p> 4) Connected ESP32 to my local computer.</p>
<p> 5) Selected appropriate board and port locations. </p>
<p> 6) Uploaded Program to ESP32 by compiling it.</p>
<p> 7) Arduino IDE has serial monitor that can actually help to monitor the outoup.</p>

<p> MicroPython is a Python 3 programming language re-implementation targeted for microcontrollers and embedded systems. MicroPython is very similar to regular Python. Apart from a few exceptions, the language features of Python are also available in MicroPython. The most significant difference between Python and MicroPython is that MicroPython was designed to work under constrained conditions.</p>

<h2> Comparison Between ESP32 & Arduino Uno Board.</h2>
<h3> Overview </h3>
<p> This week we have learned different types of microcontrollers and their languages, for this week I mostly used ESP32 microcontroller.so here for the group assignment, we are going to make a comparative report for ESP32, Arduino Uno microcontroller </p>
<h3> Methodology </h3>
<P> Myself and my group members to decide to compare ESP32 with Arduino uno. so, for this, we distributed each microcontroller among us.</P>
<p>Our focus is to compare these microcontrollers to their architecture. Started reading Data sheets of different microcontrollers under study. After completing all-important research, we put all the data in tabular format.</p>
