Displaying Sensor Data with Bluetooth
In our previous Bluetooth tutorial called Sending Sensor Data Via Bluetooth, we showed how to display data from a triple axis accelerometer over the Arduino IDE’s serial monitor. Continuing off of the first tutorial, we are going to expand this project to include more capabilities for visualizing and interacting with your accelerometer data.
