What is a INO file?

Software program created with Arduino, an open-source electronics prototyping platform; contains source code written in the Arduino programming language; used for controlling an Arduino circuit board.

More Information

Arduino programs can be used to perform basic commands, such as making an LED blink, or complex functions, such as transmitting data over the Internet. Different Arduino boards are available for specific applications.
