The Arduino Esplora looks super cool! It’s a game pad with a built-in Arduino Leonardo. It packs an ATMega 32U4, as well as sound, light, and temperature sensors, a linear pot, a buzzer, joystick, controller buttons, and RGB LED. I can’t wait to see all the cool games folks make with this thing. My only thoughts were that it should have a built-in battery pack and also, you’d have to imagine the flipside solder burrs would feel rough on your hands as you play a game.
