It's a known fact that everyday physical activity reduce health risks. Recommended amount of physical activity can be reached not only in gym, but accumulated by overall number of efforts, including steps. For different age groups there's different minimal number of steps per day.
My project will help you to check your everyday activity. You need only micro:bit, battery holder and your phone. The following steps will help you to proceed:
1. Program your micro:bit board on the platform https://en.vittascience.com/microbit/ by transferring the file on the board. Shake sensor of micro:bit has high sensitivity, so there should be added "pause" to get precise values during walking and jogging.
Shake sensor of micro:bit has high sensitivity, so there should be added "pause" to get precise values during walking and jogging. I provided an experimental comparison: during 30 min I was walking with programmed micro:bit and Mi Band 2 (that contains the function of step counter) in my pocket. As a result, I established that the optimal duration of the pause for my speed of walk is 500ms.
2. Connect micro:bit and battery.
3. My aim was to use a minimal number of components for this project, hence no extra sensors, nor Bluetooth. I created an app on Mit app inventor platform http://ai2.appinventor.mit.edu/ to analyze and share the data.
With the app you can set data and time, choose your age group and get the recommendations, make photo of your micro:bit with the number of steps and add it to the app, print the number of steps and get info about its meaning and how close you are to the recommended amount of steps, capture a screenshot and share it with your friends on social networks!
