PASCO Code.Node Manuel utilisateur

//code.Node (PS-3231)

Included Equipment

//code.Node

Micro USB cable

For connecting the sensor to a USB charger to charge the

battery or a USB port to transmit data.

Required Equipment

PASCO Capstone or SPARKvue software is required for data

collection.

Overview

The //code.Node is an input-output device that supports coding

activities to help teach how sensors work and how code can be

used to create and control a response (output) to a stimulus

(input). The //code.Node is an introductory device for STEM-

oriented programming activities performed using PASCO

software applications. The device contains five sensors and two

momentary push buttons that act as inputs, as well as three

output signals, enabling students to program how the device

collects and responds to data.

The //code.Node can sense relative light brightness, relative

sound loudness, temperature, acceleration, tilt angle, and

magnetic field. These input sensors are included to help

teaching coding concepts and highlight how collected data can

be analyzed and programmed to create unique outputs involving

its speaker, LED light source, and 5 x 5 LED array. The

//code.Node outputs are not exclusive for use only with its

inputs; the outputs can be used in code involving any PASCO

sensors and interfaces.

NOTE: All //code.Node sensors used in a given

experiment will take measurements at the same

sample rate specified in PASCO Capstone or

SPARKvue. It is not possible to set separate

sample rates for different sensors on the same

//code.Node in a single experiment.

The //code.Node sensors are meant to be used for coding

purposes and should not be considered a replacement for

science sensors in labs that use similar sensor measurements.

Sensors built to more rigorous specifications for use in science

experiments are available at www.pasco.com.

//code.Node Inputs

Temperature/Light/Sound Sensor

This 3-in-1 sensor records ambient temperature, brightness as a

measure of relative light intensity, and loudness as a measure of

relative sound level.

•The temperature sensor measures ambient temperature

between 0 — 40 °C.

•The light sensor measures brightness on a 0 — 100%

scale, where 0% is a dark room and 100% is a sunny day.

•The sound sensor measures loudness on a 0 — 100%

scale, where 0% is background noise (40 dBC) and 100%

is a very, very loud scream (~120 dBC).

NOTE: The Temperature, Light, and Sound

Sensors are not calibrated and cannot be

calibrated within PASCO software.

Magnetic Field Sensor

The magnetic field sensor only measures the strength of a

magnetic field in the y-axis. A positive strength is produced

when the north pole of a magnet is moved towards the "N" in the

magnetic sensor icon on the //code.Node.

While the magnetic field sensor cannot be calibrated in the

software application, the sensor measurement can be tared to

zero.

Button 1 and Button 2

Button 1 and Button 2 are included as basic momentary inputs.

When a button is pressed, that button will be assigned a value of

1. A value of 0 is assigned when the button is not being pressed.

Acceleration and Tilt Sensor

The acceleration sensor within the //code.Node measures

acceleration in the x- and y-axis directions, which are labeled on

the sensor icon shown on the device. The pitch (rotation around

the y-axis) and roll (rotation around the x-axis) are measured as

Tilt Angle - x and Tilt Angle - y respectively; the tilt angle is

measured to a ±90° angle in relation to the horizontal and

vertical planes.

The acceleration and tilt angle measurements of the sensor can

be tared to zero from within the software application.

Produces a positive x-tilt to

a maximum angle of 90°,

occurring when the

//code.Node is on its left

side.

Produces a positive y-tilt

to a maximum angle of

90°, occurring when the

//code.Node is standing

upright.

When placed face-up on a flat surface, tilting the //code.Node to

the left (thus rotating around the y-axis) will result in a positive x-

acceleration and a positive x- tilt angle up to 90°. Tilting to the

right will result in a negative x- acceleration and negative x- tilt

angle. Similarly, tilting the device upwards (rotating around the x-

axis) will result in a positive y- acceleration and positive y- tilt

angle to a maximum angle of 90°; tilting the device downwards

will produce negative values.

//code.Node Outputs

Within the Blockly-integrated Code tool, unique coding blocks

have been created in SPARKvue and PASCO Capstone for each

output of the //code.Node to program and control their effects.

NOTE: The use of the //code.Node outputs are

not exclusive to its inputs. These outputs can be

used in conjunction with all lines of supported

PASCO sensors.

Accessing and using the Code Blocks for

the //code.Node

Note that producing code for the //code.Node requires using

PASCO Capstone version 2.1.0 or later or SPARKvue version

4.4.0 or later.

1. Open the software and select Hardware Setup from the

Tools panel on the left (Capstone) or Sensor Data from the

Welcome Screen (SPARKvue).

2. Connect the //code.Node to the device.

3. SPARKvue only: Once the //code.Node measurements

appear, select the measurement options you intend to use,

then select a template option.

4. Select Code from the Tools tab (Capstone), or click the

Code button on the bottom toolbar (SPARKvue).

5. Select "Hardware" from the list of Blockly categories.

RGB LED

One output signal of the //code.Node is its Red-Green-Blue

(RGB) multi-color LED. The individual brightness levels for red,

green, and blue light of the LED can be adjusted from 0 — 10,

allowing for a spectrum of colors to be created.

A single block is included in Code for the RGB LED and can be

found in the "Hardware" Blockly category. A brightness of 0 for a

given color will ensure that color LED is not emitted.

Speaker

While the volume is fixed, the frequency of the //code.Node

Speaker can be adjusted using the appropriate Code blocks.

The speaker can generate sounds in a range of 0 — 20,000 Hz.

Two unique blocks are included in the software’s Code tool to

support the speaker output. The first of these blocks turns the

speaker on or off; the second block sets the frequency of the

speaker.

5 x 5 LED Array

The central output of the //code.Node is a 5 x 5 array consisting

of 25 red LEDs. The LEDs in the array are positioned using the

(x,y) Cartesian coordinate system, with (0,0) at the top left

corner and (4,4) at the lower right corner. A faint imprint of the

corner coordinates can be found at each corner of the 5 x 5 LED

Array on the //code.Node.

The LEDs in the array can be turned on individually or as a set.

The brightness of the LEDs is adjustable on a scale of 0 — 10,

where a value of 0 will turn the LED off.

Three unique blocks are included in the software’s Code tool

that support the 5 x 5 LED Array. The first block sets the

brightness of a single LED at a specified coordinate. The second

block will set a group of LEDs to a specified brightness level and

can be programmed to keep or clear previous code commands

concerning the 5 x 5 LED array. The third block is an imitation of

the 5 x 5 array on the //code.Node; checking a square is

equivalent to setting the LED at that position on the //code.Node

array to the specified brightness. Multiple squares can be

selected.

Using the sensor for the first time

Before using the sensor in the classroom, the following tasks

must be completed: (1) charge the battery, (2) install the

latest version of PASCO Capstone or SPARKvue, and (3)

update the sensor firmware. Installing the latest version of the

data collection software and the sensor firmware is necessary to

have access to the latest features and bug fixes. Detailed

instructions for each procedure have been provided.

Charge the battery

The sensor contains a rechargeable battery. A fully charged

battery will last an entire school day. To charge the battery:

1. Connect the micro USB cable to the micro USB port

located on the sensor.

2. Connect the other end of the cable to a USB charger.

3. Connect the USB charger to a power outlet.

As the device is charging, the battery indicator light will be

yellow. The device is fully charged when the light is green.
