5.1 Background Information about Micro:bit
( 1 )What is Micro:bit?
Micro:bit is an open source hardware platform based on the ARM architecture launched by British Broadcasting Corporation (BBC) together with ARM, Barclays, element14, Microsoft and other institutions. The core device is a 32-bit Arm Cortex-M4 with FPU micro-processing.
Though it is just the size of a credit card, the Micro:bit main board is equipped with loads of components,including a 5*5 LED dot matrix, 2 programmable buttons, an accelerometer, a compass, a thermometer, a touch-sensitive logo and a MEMS microphone, a Bluetooth module of low energy, and a buzzer and others. Thus, it also boasts multiple functions.
The buzzer built in the other side of the board makes playing all kinds of sound possible without any external equipment. The golden fingers and gears added provide a better fixing of crocodile clips. Moreover, this board has a sleeping mode to lower power consumption of batteries and it can be entered if users long press the Reset & Power button on the back of it. It is capable of reading the data of sensors, controlling servos and RGB lights and attaching with a shield so as to connect with various sensors. It also supports a variety of codes and graphical programming platforms, and is compatible with almost all PCs and mobile devices. It has no need to install drivers. It is of high integration of electronic modules, and has a serial port monitoring function for easy debugging. The board has found wide applications. It can be applied in programming video games, making interactions between light and sound, controlling a robot, conducting scientific experiments, developing wearable devices and make some cool inventions like robots and musical instruments, basically everything imaginable.
