This example shows how to play notes on the buzzer mounted on the Arduino Esplora. Buzzers can generate different audio signals in audible frequency ranges. A note is an audio signal at a specific frequency. If you know the frequency of the notes you want to play, you can start to compose a melody. In this example, you move the slider to generate different notes, and play them by pressing the down push-butt ...

This sketch shows you how to read and calibrate the Esplora's light sensor. Because light levels vary from one location to another, you need to calibrate the sensor for each location. To do this, you read the sensor for a few seconds, and save the highest and lowest readings as maximum and minimum. You'll use the sensor's reading to set the brightness of the LED by mapping the values to a smaller range, usi ...

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. Circuit 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 ...

This example simplifies the task of collecting data from the Esplora's accelerometer and graphing it with your computer. The Esplora sends keypresses to a connected computer about the state of the accelerometer. If you open a spreadsheet application, you can log the data from the accelerometer. To start and stop the datalogging, press the down pushbutton. The Esplora's LED will indicate the state of the log ...

This example demonstrates how to turn your Esplora into a customized computer game pad. It uses the analog joystick and the four switches as inputs to a video game. The Esplora will appear to the computer as a standard keyboard, the computer will see joystick movement and button presses as keystrokes. The configuration choosen in this example is suitable for SuperTuxKart, an open-source racing game, availab ...

This sketch shows you how to read the Esplora's temperature sensor. You can read the temperature sensor in Farhenheit or Celsius. Circuit 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. Temperature to send data to your computer from the Esplora Code To send data to your computer, you need to open a serial conn ...

This example is designed to be used with a Processing sketch. Processing is an open source programming environment. The application on the computer reads the sensors on the Esplora board and controls the buzzer and the RGB LED through a graphical interface. The image in the Processing application mirrors the Esplora board, so you'll see a virtual version of your board. If you don't have Processing installed ...

This sketch shows you how to read the microphone sensor. The microphone will range from 0 (total silence) to 1023 (really loud). It uses the sound level to set a brightness level for the green LED. When you're using the sensor's reading (for example, to set the brightness of the LED), you map the sensor's reading to a range between the minimum and the maximum. Circuit Only your Arduino Esplora is needed for ...

Want to play Pong on your computer with your Esplora? This example shows you how. This example is designed to be used with a Processing sketch. Processing is an open source programming environment. The Esplora reads the slider and buttons and sends data to the Processing sketch serially over USB, and Processing uses the incoming data to move paddles in a game of Pong. If you don't have Processing installed ...

This sketch shows you how to read information from the Esplora's joystick and use it to control the movement of the cursor on your computer. You're making your Esplora into a mouse! This sketch will take over the mouse movement of your computer. If you lose control of your cursor do the following : unplug the Esplora open the EsploraBlink sketch in the Arduino software hold the Esplora's reset button down w ...

This example shows you how to read different analog sensors to change the brightness of the three colors in the RGB LED. In this example you will read the amplitude from the microphone, the amount of light on the light sensor, and the position of the linear potentiometer. These three sensors will control the intensity of the red, blue, and green colors of the RGB LED. Circuit Only your Arduino Esplora is ne ...

This example shows you how to read the values from the joystick. The output will be displayed through the serial monitor and as a color on the RGB LED. The joystick has two axes, X and Y. Each axis controls a color of the RGB LED: red with the X-axis, and green with the Y-axis. The brightness of the blue element will be controlled by the position of the linear potentiometer. Circuit Only your Arduino Esplor ...
