microMedic Kit Demos

These quick demos were written to support special kits created for the 2013 National microMedic contest. While these kits and many of the items in them are no longer supplied by Parallax, the Propeller Spin and Arduino code examples will remain available for reference.

Pressure Sensor Arduino Demo

The Freescale MPX 5020 Pressure Sensor in the 2013 National microMedic Contest Kit can detect positive and negative air pressure changes. This tutorial connects the pressure sensor to the Board of Education Shield and uses the Serial Monitor to display data.

SpO2 Sensor Propeller Spin Demo

The Nellcor SpO2 Sensor for pulse rate and blood oxygenation is included in the 2013 National microMedic Contest Kit. This Propeller Spin demo takes readings from this sensor's photodiode while infrared and red LEDs light alternately, and displays the raw data in a Serial Terminal.

Vibra Tab Arduino Demo

The Vibra Tab is a transducer made of piezoelectric film that produces voltage when bent. This Board of Education Shield for Arduino demo displays the voltage output in the Serial Monitor.
