Share My Creation Birthday Card

Birthday card that plays happy birthday tune and display greetings on a TFT display. The speaker is a piezo buzzer and the TFT is 0.96", 80x160 pixels, ST7735 driver, SPI interface.
The name of the card receiver has to be changed in the code, the color of each letter can be set, name can be up to 6 letters, the letter number is the order it is in the array 'font'.
