Board - Specify Sampling Interval

Use the board's samplingInterval(ms) to control the actual MCU sampling rate.

Breadboard for "Board - Specify Sampling Interval"

 

Run this example from the command line with:

node eg/board-sampling-interval.js

const { Board } = require("johnny-five");
const board = new Board();

board.on("ready", () => {

  // Use the board's `samplingInterval(ms)` to
  // control the actual MCU sampling rate.
  //
  // This will limit sampling of all Analog Input
  // and I2C sensors to once per second (1000 milliseconds)
  board.samplingInterval(1000);


  // Keep in mind that calling this method
  // will ALWAYS OVERRIDE any per-sensor
  // interval/rate/frequency settings.
});
