BitPlayer provides you inspiration and excitement to make creations such as a portable piano or a smart calculator. To be easier to carry and use, BitPlayer abandoned an allbutton design that a typical game controller would use in favor of a 2-axes joystick. It includes another 6 programmable buttons labeled as L, R, A, B, C and D. Besides, the BitPlayer itself features a buzzer, a vibration motor and a Grove I2 C port to give kids lively and interactive experience of game. You can easily enjoy DIY projects anywhere by installing 2 AAA batteries into the BitPlayer. As tested already, BitPlayer can interact with other devices when Bluetooth positioning is within a distance range about 10 meter.
