The Arduino Esplora is a microcontroller board derived from the Arduino Leonardo. The Esplora differs from all preceding Arduino boards in that it provides a number of built-in, ready-to-use setof onboard sensors for interaction. It's designed for people who want to get up and running with Arduino without having to learn about the electronics first. For a step-by-step introduction to the Esplora, check out the Getting Started with Esplora guide.

The Esplora has onboard sound and light outputs, and several input sensors, including a joystick, a slider, a temperature sensor, an accelerometer, a microphone, and a light sensor. It also has the potential to expand its capabilities with two Tinkerkit input and output connectors, and a socket for a color TFT LCD screen.

Specifications:

• Microcontroller ATmega32u4
• Operating Voltage 5V
• Flash Memory 32 KB of which 4 KB used by bootloader
• SRAM 2.5 KB
• EEPROM 1 KB
• Clock Speed 16 MHz
• Analog joystick with central push-button two axis (X and Y) and a center pushbutton.
• 4 push-buttons laid out in a diamond pattern.
• Linear potentiometer slider near the bottom of the board.
• Microphone for getting the loudness (amplitude) of the surrounding environment.
• Light sensor for getting the brightness.
• Temperature sensor reads the ambient temperature
• Three-axis accelerometer measures the board's relation to gravity on three axes (X, Y, and Z)
• Buzzer can produce square-waves.
• RGB led bright LED with Red Green and Blue elements for color mixing.
• 2 TinkerKit Inputs to connect the TinkerKit sensor modules with the 3-pin connectors.
• 2 TinkerKit Outputs to connect the TinkerKit actuator modules with the 3-pin connectors.
• TFT display connector connector for an optional color LCD screen, SD card, or other devices that use the SPI protocol.
• Resettable polyfuse that protects PC USB ports from shorts and overcurrent.
