Mini leds widget

[wanek]

wow, that is really cool trick…
one can use to make a nice progress bar indicator

[Blynk_Coeur]

yes and many other things like big display

[wanek]

those full and empty circles are ascii code? i can’t find such character in ascii table…

[Blynk_Coeur]

ah ah, there are not ascii code, but you can too

this is my strings

String Led1 = "🌑🌑🌑🌑🌑🌑🌑"; // all low
String Led2 = "🌕🌑🌑🌑🌑🌑🌑";
String Led3 = "🌕🌕🌑🌑🌑🌑🌑";
String Led4 = "🌕🌕🌕🌑🌑🌑🌑";
String Led5 = "🌕🌕🌕🌕🌑🌑🌑";
String Led6 = "🌕🌕🌕🌕🌕🌑🌑";
String Led7 = "🌕🌕🌕🌕🌕🌕🌑";
String Led8 = "🌕🌕🌕🌕🌕🌕🌕";//all high

@Blynk_Coeur

I just created this function called MiniLed()

code tease

@Blynk_Coeur

not ascii code, but you can too
this is my strings

What are they? I can copy/paste into my IDE, but the display widget clearly doesn’t understand what to do with them.

[Blynk_Coeur]

I am using Android 6.0
don’t know why such result for you Gunner
what do you see on your serial monitor ?

[Blynk_Coeur]

[Gunner]

@Blynk_Coeur

what do you see on your serial monitor ?

Same thing… 6 little ??????

But if I copy/paste from your post above into my display widget setup like you did, I can also display the “whatevertheyare” characters… just not via the script.

[Blynk_Coeur]

void MiniLed() {

  LedFlag++;
  if (LedFlag == 9) {
    LedFlag = 1;
  }
  Serial.println( LedFlag);
  
  switch (LedFlag)
  {
    case 1: { // Item 1
        Blynk.virtualWrite(V16, Led1);
        break;
      }
    case 2: { // Item 2
        Blynk.virtualWrite(V16, Led2);
        break;
      }
    case 3: { // Item 3
        Blynk.virtualWrite(V16, Led3);
        break;
      }
    case 4: { // Item 4
        Blynk.virtualWrite(V16, Led4);
        break;
      }
    case 5: { // Item 5
        Blynk.virtualWrite(V16, Led5);
        break;
      }
    case 6: { // Item 6
        Blynk.virtualWrite(V16, Led6);
        break;
      }
    case 7: { // Item 7
        Blynk.virtualWrite(V16, Led7);
        break;
      }
    case 8: { // Item 8
        Blynk.virtualWrite(V16, Led8);
        break;
      }
  }
}

[Blynk_Coeur]

this my serial

[Blynk_Coeur]

it is an issue between copy and past

try to get full_moon and new_moon smiley

[Gunner]

Of course Phone emoticons!!!.. I should have guessed since I use them all the time in my testbench project.

[Blynk_Coeur]

yes phone emoticons
you can use extended ASCII code as well.
but not so nice

[Gunner]

Yes, the only way I could code it in my IDE was like this

String Led1 = "\xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91"; // all low
String Led2 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91";
String Led3 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91";
String Led4 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91";
String Led5 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91";
String Led6 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x91 \xF0\x9F\x8C\x91";
String Led7 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x91";
String Led8 = "\xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95 \xF0\x9F\x8C\x95";//all high

BLYNK_WRITE(V54) {
  switch (param.asInt())
  {
    case 1: { // Item 1
        Blynk.virtualWrite(V58, Led1);
        break;
      }
    case 2: { // Item 2
        Blynk.virtualWrite(V58, Led2);
        break;
      }
    case 3: { // Item 3
        Blynk.virtualWrite(V58, Led3);
        break;
      }
    case 4: { // Item 4
        Blynk.virtualWrite(V58, Led4);
        break;
      }
    case 5: { // Item 5
        Blynk.virtualWrite(V58, Led5);
        break;
      }
    case 6: { // Item 6
        Blynk.virtualWrite(V58, Led6);
        break;
      }
    case 7: { // Item 7
        Blynk.virtualWrite(V58, Led7);
        break;
      }
    case 8: { // Item 8
        Blynk.virtualWrite(V58, Led8);
        break;
      }
  }
}

But it works great!

[Blynk_Coeur]

it works well!

@Gunner

I should have guessed since I use them all the time in my testbench project.

I totally should have caught on sooner… as I used similar emoticon control for animated displays

[SOLVED] Add image or my icon to widget blynk

Well, this makes for some interesting options… such as “animated” icons… [image] void clockDisplay() // requires RTC setup and a timer call every second { sprintf(currentTime, "%02d:%02d:%02d", hour(), minute(), second()); // Send 1st hourglass icon and time to Display Widget Blynk.virtualWrite(V12, "\xE2\x8F\xB3", currentTime); // Send 2nd hourglass icon and time to Display Widget 1/2 second later timer.setTimeout(500L, []() { Blynk.virtualWrite(V12, "\xE2\x8C\x9B", curren…

[Gunner]

PS, this is where I get my emoticon codes from…

Emoji unicode characters for use on the web

[Blynk_Coeur]

i use a similary website.

[Emilio]

Interesting graphical coding approach!! Thanks for sharing
