Esplora Accelerometer

This sketch shows you how to read the values from the accelerometer. To see it in action, open the Arduino serial monitor on your computer and tilt the board. You'll see the accelerometer values for each axis change as you tilt the board.

Hardware Required

  • Arduino Esplora


Only your Arduino Esplora is needed for this example. Connect the Esplora to your computer with a USB cable and open the Arduino's Serial Monitor.

Accelerometer to send data to your computer from the Esplora


To send data to your computer, you need to open a serial connection. use Serial.begin() to open a serial port at 9600 baud on the Esplora.

The Esplora.readAccelerometer() function gets the values from the accelerometer. It needs an argument telling it what axis you're reading from: X_AXIS, Y_AXIS, or Z_AXIS. Each axis will give you a value between 0 and 1023.

To send the values to the Serial Monitor, you call Serial.print(). When the Esplora is connected, and the Serial Monitor is open, you should start to see values reported like this twice a second :

x: 6	y: -128	z: 27
x: 2	y: -138	z: 19
x: 9	y: -137	z: 20
