This work is a simple pedometer design. It mainly uses MEMS sensors to detect changes in human body posture. It uses a pedometer algorithm to implement a simple pedometer function. It uses an OLED screen as a display device and adds a GY-30 light sensor module to detect changes in brightness of the surrounding environment. To adjust the OLED backlight brightness in real time; at the same time, the on-chip RTC is used to realize the real-time clock function. Due to limited time resources, it can be expanded later to add heart rate detection, temperature, humidity and air pressure, voice playback and networking functions.
"Portable information board", as the name suggests, displays the information you want to display on a device (screen) that you carry with you. The inspiration for this idea was that I met many elderly people who were lost before, but some of them were too old, had poor memory, forgot where their home was, couldn’t find their family members’ phone numbers, etc. (Although there are only a few, they are still exists, and China’s population is aging increasingly, so the proportion will inevitably increase).

i.MX RT1064 EVK is a 4-layer through-hole USB powered PCB. The core of the board is the i.MX RT1064 crossover MCU, which uses NXP’s advanced Arm® Cortex®-M7 core implementation. The core runs at speeds up to 600 MHz, providing high CPU performance and excellent real-time response.
The Bluetooth base station designed this time for smart running shoes is mainly used in school classrooms, gyms and other places. Taking school classrooms as an example, schools and parents pay attention to students' daily exercise and learning status, and balance work and rest. Students put on smart shoes and place Bluetooth base stations in the classroom. Without getting rid of mobile phones, each student's movement status can still be collected that day. When students attend class, the base station automatically connects to the smart shoes via Bluetooth and obtains the step count, and stores the student ID and step count. After the day's class, the teacher can use the PC software to check the status of the students that day. During the class, the teacher can also use the PC software to control the connection to the designated smart shoe device.
