Introduction

The extension allows the user to control the RGB LED display of Quarky.

Connecting Quarky with PictoBlox

Let’s begin by first connecting Quarky to PictoBlox. Select your preferred type of device i.e. either the desktop/laptop or your smartphone and follow the instructions.

Desktop

Follow the steps below for connecting Quarky to PictoBlox:

  1. First, connect Quarky to your laptop using a USB cable.
    Power Quarky
  2. Next, open PictoBlox on your desktop.
  3. After that, select Block or Python Coding as your coding environment.
  4. Then, click the Board button in the toolbar and select board as Quarky.
  5. Next, select the appropriate Serial port if the Quarky is connected via USB or the Bluetooth Port if you want to connect Quarky via Bluetooth and press Connect.
    COM Port

And voila! Quarky is now connected to PictoBlox.

Mobile

Follow the steps below for connecting Quarky to PictoBlox:

  1. First, power ON Quarky.
  2. Open PictoBlox on your smartphone. Go to My Space and make a new project by clicking the ‘+(plus)’ button in the bottom-right corner.
    PictoBlox in Mobile Phone
  3. Then, tap the Board button in the top-right corner of the toolbar.
    PictoBlox BoardSelect board as Quarky.
  4. Next, tap the Connect button:
    PictoBlox ConnectSelect your device from the list.

And voila! Quarky is now connected to PictoBlox.

Stage Mode

Stage mode is one of the two modes you can write your programs in Pictoblox. In this mode, you can write scripts for the sprite and boards to interact with sprites in real-time. If you disconnect the board with Pictoblox, you cannot interact with the board anymore. In this mode, you can make games and animation interacting with Quarky.

You can toggle between the upload mode and stage mode using the button on the top right side of Pictoblox.

Note:  You have to upload the firmware into the device before interacting with it. Please refer this doc: https://ai.thestempedia.com/docs/updating-quarky-firmaware-with-pictoblox/

In Python Coding Environment, use the following object declaration to use Python functions in Stage Mode:

quarky = Quarky()

Upload Mode

Upload mode is one of the two modes you can write your programs in Pictoblox. This mode allows you to write scripts and upload them to the board so that you can use them even when it is not connected to your computer, for example, you need to upload a script for making moving robots.

In this case, Quarky will run offline according to the program and it can not interact with the stage.

In Python Coding Environment, use the following object declaration to use Python functions in Upload Mode:

from quarky import *

PictoBlox Blocks

The block writes the message to the RFID tag. It will wait for the specified time to scan an RFID tag and write the value on it. The block also reports whether the operation is completed or not. If the write is complete the block returns 1, else it returns 0.
The block defines the value of the body.
This block allows the Gripper Robot to open its gripper.
This block is used to get the angle of a selected servo connected to a robotic arm.
The block gives the value of the current sensed on the sensing ports of evive in mili-Ampere.  
() music file ()
The Music module allows you to play tones, songs and other recorded audio files from your phone’s storage as per command send from the hardware device. This block is used to play the audio file for the key entered in the text box of the block.
get current position block
This block reports the current position of the end effector in the selected axis.
The block holds its sprite’s X position. This block can be displayed as a Stage monitor.
If the block’s sprite is shown, it will hide the sprite. If the sprite is already hidden, nothing happens.
It reports the number of days (and fractions of a day) since 00:00:00 1 January 2000 (UTC).
The block rounds the given number to the nearest integer. It follows the standard rules of rounding; decimals that are .5 or higher are rounded up, whereas decimals less than .5 are rounded down.
The block hides the specified list’s Stage monitor.
The block reports the x velocity of the sprite.
The block set the last scanned RFID tag to the master RFID tag. This can be used for authentication.
The block sets the body content type to the specified value.
The block resets the timer running for the oscillator to 0.
This block allows the Gripper Robot to close its gripper.
The block reports the current position of the end effector along the X, Y, and Z axes.
The block returns the time passed since the device is turned ON or since the timer has been reset. This block returns time in milliseconds.
The Camera module allows you to use your mobile camera for different activities like recording videos, capturing images, color detection, and face detection. This block sends commands for clicking an image, starting the video, and stopping the video in the camera module.
clear notification
The Notification module of the IoT module triggers a notification in your Smartphone based on events occurring on your hardware. This block is used for clearing the previous notifications from the phone.
The block holds its sprite’s Y position. This block can be displayed as a Stage monitor.
The block will place a sprite in front of all other sprites. It does this by changing the sprite’s layer value.
The block performs a specified function on a given number and reports the result. The function can be changed by clicking the down arrow and selecting a new function from the drop-down menu.
The block reports the y velocity of the sprite.
The block reports if the last RFID tag scanned is a master tag or not. If it is the master RFID tag, then it returns true, else false.
The block reports the time passed from the reset for the oscillator.
reset timer
The block sets the timer’s value back to 0.0. Usually, the timer must be reset at the beginning of a project for the Timer block to hold the right value.
The Oscilloscope module allows you to visualize the input and output signals of your hardware device on your smartphone. This block for setting the baud rate of the Bluetooth module that you have connected to Arduino Mega.
The block holds its sprite’s direction, measured in degrees.
