Using Arduino Uno WiFi

Programming via OTA

Programming via OTA (Over-the-Air) is not supported on the Arduino Uno, as it does not have a built-in WiFi or Bluetooth module. However, you can add a compatible third-party WiFi shield to your Arduino Uno and use programs that support OTA functions. To do this, you will need to acquire the necessary hardware and download any additional software needed to enable OTA programming.

Once all of these components are in place, you should be able to program your Arduino over the air with minimal effort.

Please note that while some popular boards such as the Raspberry Pi may offer wireless programming through their integrated WiFI modules, this capability is generally not available on most standard microcontroller platforms, including the Arduino Uno. As such, if you would like to take advantage of OTA programming capabilities, you will need to purchase and install the necessary additional hardware.

In addition to the Arduino Uno, there are some other microcontroller platforms that do not have built-in WiFi or Bluetooth support but nonetheless still offer Over-the-Air (OTA) programming. For example, the ESP8266 NodeMCU board is a popular choice for those looking to develop projects using OTA firmware updates. The ESP8266 NodeMCU also has an integrated WiFI module which simplifies the process of connecting your device over the air and uploading new code without having to physically plug in any cables. As always, be sure to check with specific product documentation before setting up your project. [2]
