The sport of unicycling is an emerging competitive sport. The sport of unicycling has gone through a process of development from amusement to the acrobatic stage and then to the sports field. At present, the sport has spread to 220 countries and regions around the world, and the world unicycle competition has been held 6 times. In August this year, the 7th World Unicycling Championships were held in New York, USA. Unicycling is very beneficial to improve strength, speed, endurance, agility, flexibility, and other physical qualities, and can improve overall balance, mediation muscle tension, etc.
Now, we make a unicycle device with block pellets and use micro:bit, Nezha Breakout Board , and PlanetX sensors so that the acrobat in the unicycle device can move around in a circle and record the number of laps.
