|
|
*
|
|
* Note: this sensor must be driven at 3.3V only.
|
|
*
|
|
* This module simply spits out the ADC values reported by the sensor, with
|
|
* the intent to send that data, via serial or network port, somewhere to
|
|
* another piece of software running on a computer that plots the data for
|
|
* you, like an EKG.
|
|
*
|
|
* Processing (https://www.processing.org/) is software
|
|
* that should work, using information from the SparkFun* website.
|
|
*
|
|
* This example just dumps the raw data:
