1. and interesting component module configuration 2. Various cases 3. Based on the BBC :bit development board -bit is an ARM architecture microcontroller designed by the British BBC. It is only half the size of a credit card, with onboard Bluetooth, accelerometer, electronic compass, three buttons, 5X5 LED dot , microphone, etc. It is mainly used for programming education for teenagers 4. Advanced Python programming Python language is easy to learn, universal and portable. It is a popular choice for transitioning from graphical programming to code programming. It is suitable for advanced programming for teenagers over 12 years old. 5. In order to facilitate the learning of :bit, we have specially equipped this learning kit. The kit includes LED, buzzer, water level sensor, sound sensor, steering gear, LCD display, ultrasonic sensor, digital tube and other characteristic sensors and modules, covering different topics of electronic system design. We also provide :bit learning courses based on these components. The courses include experimental principle explanations, wiring methods, experimental codes and instructions, so that you can have a good understanding of these electronic components and -bit, starting from a simple single sensing elements Experiments to complex multiple component combination experiments will guide you to play with :bt and learn programming .
