Introduce Arduino IDE Software

I Will already Share the Arduino IDE Software Link https://www.arduino.cc/en/software You just Download the software And Open it Depending on your Operating System.

Explanation IDE

Just install the Software and open It then you sell like this ….

you just open the IDE And go to the tools and you see the different Boards Available, You Just Select the board Correctly

On the Left Side, you see the verify and upload Symbol Available

if you type the code in the editor and you want to check whether the code will generate an error or not you just click the verify button then our code will compile and find the error.
if you want to Upload the code in the microcontroller you just click the Uploading Button first you select the proper board and port.

On the Right Side, You just see the corner of the Serial monitor and Serial Plotter Available

Started With Arduino Nano Board
