'''Arduino is not detected by your computer'''
This is a very common probl
em encountered by most Arduino beginners and, on occasion, by those with intermediate Arduino experience. Your IDE will not recognize the connected Arduino board, and your device manager will report "unknown USB device". To fix it, you may need to download and install the CH340G drive.
* Download the driver from [http://www.wch-ic.com/downloads/CH341SER_ZIP.htm http://www.wch-ic.com/downloads/CH341SER_ZIP.html]
* It will ask for administrator permissions, click YES.
* Now it will prompt you with 3 options: Install, uninstall and help. Click on INSTALL
* Once the driver installed it says “Driver Install Success”.
* Restart your computer after installation (Important).
'''Program/sketch not uploading solutions'''
These are the possible causes of the failure to upload the sketch to Arduino.
* Wrong COM port selected : People occasionally select the incorrect COM port. Each computer has a unique COM port number, and you must select the correct one for your computer.
* Selected wrong board at tools menu : You have to select the correct board option. For instance, if you choose Arduino Nano for Arduino Uno, your code will upload.
* Defective USB port : Connect your Arduino board to a good USB port on your computer and check for physical flaws in the USB port on the Arduino board. Connect to a different USB port on your computer.
* Inspect for physical damages on Arduino board : Microcontrollers or other passive or active components may have flaws that are not physically inspectable or changeable; in this case, replace the entire board.
To fix some other problems, try Reinstall the Arduino IDE or try to upload a sketch from another computer
