Programming the SparkFun Edge with Arduino
Running low-power machine learning examples on the SparkFun Edge can now be done using the familiar Arduino IDE. In this follow-up to the initial Edge tutorial, we'll look at how to get three examples up and running without the need to learn an entirely new SDK.
Sending Sensor Data via Bluetooth
In this tutorial, we will show you how to get started on incorporating Bluetooth into your electronics projects. This project uses a SparkFun Thing Plus ESP32 Wroom USB-C to display data from a Triple Axis Accelerometer over Bluetooth.
