Welcome to the Meadow TensorFlow Library. This library provides a .NET application using the TensorFlow Lite Micro, a powerful tool using machine learning on microcontrollers. The Meadow TensorFlow implements the most common TensorFlow API in C# which allows .NET developers to develop and deploy Machine Learning models on Meadow Devices.
Demonstrate the absolute basics of using TensorFlow. This demo will predict the output of the sine function.
The expected output of the Hello World demo.
