Week 11 Input

  • Assignment measure something: add a sensor to a microcontroller board that you have designed and read it

    • Hello Light 45 / Phototransistor 1206

    Light Phototransistor. It will be an imput device that I will use to detect the shadow on passage of the ball after the goal in footballino.

    Programming the board
Connect to FabISP
Connect FTDI cable for power
Copy C program and make-file to a folder

by windows command prompt go into the directory where the file

make -f namemakefile.make program-usbtiny

    Testing the Board
Install python-tk (tkinter library)
Download python file from Neil's examples
into the same the directory command

type: python hello.light.45.py COM (number)

    Footballino

    For my final project I decidet to design and mill a customized version of FABLEO

    Here how a FABLEO look like

    In my version, the pin are moved on top and i decide to reduce the size of the board because i need to install it in a veri narrow place in between of the wood frame of the table.

    Here my version of Footballino01 with pin moved and space reduced. I decide to mantain a reset button because it could be usefull in uncertain conditions.

    Footballino is customized Fableo

    Here the Pin scheme for ATMEGA32U4

    Hey! my Footballino is blinking

    Footballino 1.2 - SDA_SCL

    After some weeks I decidet to add a SDA (A4/PC4) and SCL (A5/PC5) pin and the first attempt was to create two holes with the Dremel and solder two wires ... The attempt failed and of course I saved the card by a miracle !

    SDA and SCL hand made holes

    Footballino connected to the LCD Screen works well!! but seems I need some more pin or some other solution.
    The long story of output LCD...

    After my bad experience with a hand made hole I decide to redesign and weld a new version of Footballino withc contain by default the SDA and SCL pin for my LDC table Display

    Footballino 1.2 milled!

    Unfotunatly time is running and I have to use a commercial board in my final project but I am going to sold and programming it as soon as possible.

    Arduino

    The trigger for Machine Assignment

    From the Machine Assignment I focus my idea to a simple input board like a hello.button

    Input output - LDR e Servo


    The Button Board

    Switch sensor Is an imput device that I will use to detect the pressure of the ball after the goal.
