Tell us about your project:

My project is a Display with LEDs.

Besides scrolling text my project displays rotating borders and images.

All three functions can be accessed using 2 switches, so it is a four-state display.

The images displayed are easily created by using the links given below:

 

My question is: How do I automatically send the *.ino file to Arduino? When I download it to the computer I want Arduino to start running it. Do I need an Ethernet Shield?

 

Are there any links or files you'd like to provide that support your project?  Code snips, 3d print files, etc.

 

Border Display

 

int scrollspeed = 50;

int flag=0;

//Columns

int clockPin1 = 2; //Arduino pin connected to Clock Pin 11 of 74HC595

int latchPin1 = 3; //Arduino pin connected to Latch Pin 12 of 74HC595

int dataPin1 = 4;  //Arduino pin connected to Data Pin 14 of 74HC595

 

 

//Rows

int clockPin2 = 5; //Arduino pin connected to Clock Pin 11 of 74HC595

int latchPin2 = 6; //Arduino pin connected to Latch Pin 12 of 74HC595

int dataPin2 = 7;  //Arduino pin connected to Data Pin 14 of 74HC595

 

 

//BITMAP

 

byte bitmap1[5][3]={

  {170,170,170},

  {0,0,1},

  {128,0,0},

{0,0,1},

  {170,170,170}

};

byte bitmap2[5][3]={

   {73,146, 4},

  {128,0,1},

  {0,0,0},

  {128,0,1},

  {36, 73, 255}

};

byte bitmap3[5][3]={

   {36,73,2},

  {128,0,1},

  {0,0,0},

  {128,0,1},

  {73, 146, 255}

//FUNCTIONS

// Displays bitmap array in the matrix

void RefreshDisplay()

{

  for (int row = 0; row < 5; row++) {

    int rowbit = 1 << row;

    digitalWrite(latchPin2, LOW);//Hold latchPin LOW for transmitting data

    shiftOut(dataPin2, clockPin2, MSBFIRST, rowbit);   //Transmit data

 

 

    //Start sending column bytes

    digitalWrite(latchPin1, LOW);//Hold latchPin LOW for transmitting data

 

 

    //Shift out to each matrix

    for (int zone = 0; zone < 3; zone++)

    {

      switch (flag){

        case 0:

      shiftOut(dataPin1, clockPin1, MSBFIRST, bitmap1[row][zone]);

      break;

      case 1:

      shiftOut(dataPin1, clockPin1, MSBFIRST, bitmap2[row][zone]);

      break;

      case 2:

      shiftOut(dataPin1, clockPin1, MSBFIRST, bitmap3[row][zone]);

      break;

      }

    }

   //flip both latches at once to eliminate flicker

    digitalWrite(latchPin1, HIGH);//Return the latch pin 1 high to signal chip

    digitalWrite(latchPin2, HIGH);//Return the latch pin 2 high to signal chip

    //Wait

    delayMicroseconds(50);

  }

}

// Plot each character of the message one column at a time, updated the display, shift bitmap left.

void XProcess()

{

 

      for (int refreshCount = 0; refreshCount < scrollspeed; refreshCount++)

      {

        RefreshDisplay();

 

          }

        }

 

void loop() {

  flag=(flag+1)%3;

  XProcess();

}

  • Okay this video might be a bit away from what we usually do on element14presents, but I really enjoyed listening to you image Would have loved to see the LED matrix earlier to understand what you mean with showing pictures - but I got it in the end. I said somewhere else that cardboard aided designs can be enjoyable too, it's not always necessary to 3D print a case for something. Now I want to see the streets and all the shops with their LED matrices - are they all handmade and programmed?

     

    Thank you for sharing your project and good luck with the contest!

    Thank you I hope so too.

    This is the first time that I take part in element14 presents, next time I will be more attuned to the community and hopefully not in lockdown.

    This is a product that I am still working on (by myself) and it is nowhere to be found yet (except on Facebook and other social media). Like I said it will be foldable (to go from writing to images), will display colors, and will have an on/off remote control.

    So the final product will be (and already is) programmable. If it will be handmade or made by machines is hard to tell at this moment. Now my greatest wish is to finish the prototype. The *.ino of a display can be downloaded from the first link listed above.

    In the end the user can create unique displays by combining borders with pictures.

    I hope users can be non-shop owners too, it might help some people to display a simple message like this, rather than use sophisticated electronics.

    I hope someday such products will strengthen communities because everybody can see what is displayed and it can help a user who might for instance be in some kind of trouble.

     

    In the end, it could have more states, not just 4, and some of those could be saved images. 'A picture is worth a thousand words' they say. An emoticon of I'm sick or I'm lonely or I'm scared can be life-saving to someone someday.

     

    I hope people can see the uniqueness of my product. In grad school we were taught to give credit where credit is due, I did. I hope everybody did the same.
