In this challenge, students are asked to consider the impact of people suffering from heart conditions, both to the individual and to wider society. They then generate ideas for using programmable systems to improve people’s health, and to monitor themselves.
A video introduces the idea of a heart rate monitor, and a link is made to other Faraday resources that would work well with this one. Some students will create their own design criteria from this process.
A prototype heart rate monitor is then created using a BBC micro:bit and appropriate input and output devices. The built-in accelerometer is used to detect the movement caused by heart beats, and the LED display is coupled with a beeper to output.
A sample program is included, built in the Touch Develop environment.
As an extension activity students are then challenged to integrate the device into a complete wearable product.
