The latest liquidcrystal library added support for making your OWN cool characters, this was used to make the really cute ‘degrees’ symbol (above). Here’s a site that makes the code for you!

  1. This is great! But “really cute”. There’s no hearts, flowers, rainbows, unicorns, or little ponies with freakishly long manes and tails.

  2. Here’s cute:

    #include <LiquidCrystal.h>

    LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

    byte newChar[8] = {

    B01010,
    B10101,
    B10001,
    B01010,
    B00100,
    B00000,
    B00000,
    B00000
    };

    void setup() {
    lcd.createChar(0, newChar);
    lcd.begin(16, 2);
    lcd.write(0);
    }

    void loop() {}

  3. We have a heart symbol here

    but we think the degree symbol is cuter

  4. That’s cool; though for the example, there’s already a (not quite as round/nice) degrees symbol available on most HD44870-based LCD controllers, character 0xdf.
