Arduino IOT Controller is a Chrome extension that simplifies the process of connecting and controlling IoT devices such as Arduino, Nodemcu, Esp8266, and Raspberry Pi. With this extension, users can easily transfer data to their microcontrollers and enjoy the following advantages:

1) Reduce Development Time: Arduino IOT Controller streamlines the development process by providing a user-friendly interface for connecting and controlling IoT devices. This saves valuable time for developers.

2) No Server Cost: Unlike other IoT solutions, Arduino IOT Controller does not require users to set up and maintain a server. This eliminates the need for additional expenses and technical expertise.

3) Cross Platform: The extension is compatible with multiple platforms, allowing users to connect and control their devices from different operating systems.

4) Data Transmission: Arduino IOT Controller ensures seamless data transmission between the user's computer and the connected IoT devices. This enables real-time monitoring and control of the devices.

5) Minimal Delay: The extension is designed to minimize delay in data transfer, ensuring prompt and responsive control of the connected devices.

Please note that this is the free version of Arduino IOT Controller, which allows users to create a maximum of 5 controllers.
