Future Vision : A New Era in Robotics Education

What is it?

It allows you to control the leds, RGB led, buttons and 8x8 led matrix on your Arduino board with Python language.

You can control Arduino with computer vision using your host computer and facilitate computer vision on a Raspberry Pi board.

A Darwin Future Vision mobile app created for the library allows you to control your iPhone phone's observational hardware: its flash, screen brightness and speaker volume ratio.

It pulls iPhone hardware information about the phone's screen brightness, speaker volume ratio, and which volume button is pressed, allowing you to retrieve and use this data in your python code

You can control 5 led graphs in the LEDs section of the iPhone app.

With the iPhone app, you can send data to your python code or see the data you send from your python code in the app.

What is the Goal

It aims to reawaken children's curiosity in robotics education and break new ground in robotics education by going beyond the classical robotics education.

Modular and Features

With the Arduino module of the Future Vision library, you can control the LEDs, RGB LEDs and 8x8 LED matrix on Arduino using Python language, and also read values from the buttons connected to the analog pins of Arduino.

With the Raspberry Pi module of the Future Vision library, you can read and control the LEDs, RGB LEDs, 8x8 LED matrix on the Sense HAT and Sense HAT sensors on the Raspberry Pi, you can also read the Sense HAT joystick values.

With the Vision module of the Future Vision library, you can create your own sign language, detect hands, detect happiness and unhappiness on your face, detect the instantaneous number of faces in a room, detect colors, detect whether eyes are closed or open, manage keys on the keyboard, measure volume, make your computer talk, analyze left and right arm movements, recognize objects and perform personal face recognition.

With the iPhone module of the Future Vision library and the mobile app, you can control your iPhone's observational hardware: flash, screen brightness and speaker volume. You can also see the screen brightness, speaker volume ratio and volume up or down button presses data on your computer and control your Arduino or Raspberry Pi board based on this data, or you can control your phone's flash with Arduino and Raspberry Pi, for example, by pressing the button.

Using Modules

Arduino

In order for the Future Vision library to work correctly with your Arduino Uno board, you need to install the FutureVision-Arduino.ino code on your Arduino Uno board.

Pins 13, 12 and 11 are dedicated to LED matrix, pins 10, 9, 8 are dedicated to RGB LED. You can only use pins 7, 6, 5, 4, 3, 2 as digital outputs.

Led on and off

from futurevision import arduino
uno=arduino.Arduino(usb_port="/dev/cu.usbmodem101",baud=9600)
uno.on(pin=7)
uno.wait(1)
uno.off(pin=7)

LED connections are as follows.

RGB Led Controlled

Colors you can display on RGB LED:

1. Red 🔴
2. Yellow 🟡
3. Green 🟢
4. Blue 🔵
5. Purple 🟣
6. White ⚪️
7. Light Blue 🩵

You can turn off your RGB led by entering one of these parameters: clear & off

Pin layout of the RGB LED: R:10 G:9 B:8

from futurevision import arduino
uno=arduino.Arduino(usb_port="/dev/cu.usbmodem101",baud=9600)
uno.rgb_led("red")
uno.wait(1)
uno.rgb_led("yellow")
uno.wait(1)
uno.rgb_led("green")
uno.wait(1)
uno.rgb_led("blue")
uno.wait(1)
uno.rgb_led("purple")
uno.wait(1)
uno.rgb_led("white")
uno.wait(1)
uno.rgb_led("clear")
uno.wait(1)

RGB LED connections are as follows.

Reading Button Value

The values of the buttons are set to be read only from analog pins. The returned button value will be given as {PIN}. For example, let's say we have two buttons connected to pins A0 and A3. When we press the A3 pin three times and press the button on the A0 pin twice, the terminal output will be as follows.

from futurevision import arduino
uno=arduino.Arduino(usb_port="/dev/cu.usbmodem101",baud=9600)
while True:
    read=uno.read()
    print(read)

Terminal Output

The button connections are as follows.

Led Matrix Controlled

Pin Layout of Led Matrix: DIN:13, CS:12, CLK:11

You can show any characters you want in Led Matrix. The character and shape list is as follows:

A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U, V, W, X, Y, Z

a, b, c, d, e, f, g, h, i, j, k, l, m, n, o, p, q, r, s, t, u, v, w, x, y, z

1, 2, 3, 4, 5, 6, 7, 8, 9, 0

+, -, *, /, %, %, =, up, down, right, left, happy, unhappy, heart

You can turn off your led matrix by entering one of these commands: clear & off

Led Matrix is set to run vertically by default. To change this, you can change the direction parameter to 0.

Example: uno.show_led_matrix("A",0)

from futurevision import arduino
uno=arduino.Arduino(usb_port="/dev/cu.usbmodem101",baud=9600)

upper_letter_list=['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']

number_list=[1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
sign_list=['+', '-', '*', '/', '%', '=', 'up', 'down', 'right', 'left', 'happy', 'unhappy', 'heart']

for i in upper_letter_list:
  uno.show_led_matrix(i)
  uno.wait(1)
  uno.show_led_matrix("clear")

for i in lower_letter_list:
  uno.show_led_matrix(i)

Application Sections and Sample Codes

Settings

In the Settings section, you should save the IP address and port information that your Python code will give you so that the application can communicate with the Python code you will write.

HWC

In this section, the iPhone module of the Future Vision library allows you to control the observational hardware of your iPhone based on the code you write. It allows you to control the Flash with flash_on() and flash_off() functions, the Screen Brightness with screen_brightness(value) function, and the Speaker Volume with volume_intensity(value) function.

CwH

In this section, the iPhone module of the Future Vision library sends the observational hardware information of your iPhone to your python code as a list. You can read this list data with the read_data() function. The sample data list includes the screen brightness value, the volume value and the volume key pressed on your phone:

['25', '70', 'Down']
['25', '75', 'Up']

LEDs

In this section, the iPhone module of the Future Vision library allows you to control the 5 led graphics in the application according to the codes you write with the iPhone module and you can change the colors of the 5 leds to green, blue and red. You can use led_on(pin) to turn on the leds in the application and led_off(pin) to turn them off.

SEND&SHOW

In this section, according to the codes you will write with the iPhone module of the future vision library, you can send the data you will enter in the input in the application to your computer or send data from your computer to the mobile application. you can use send_data(data) functions to send data to the mobile application and read_data() functions to read the data sent by the mobile application.
