Today is that Day where everybody exchange their love by making a gift to the loved one!

In this way I make a new sketch for KeyChainino in order to create a particular gift that you can give to your lover.

The sketch is really simple. It shows the phrase: “Happy San Valentine’s Day” – which you can customize how you wish – next it blinks the Heart ❤️  for few milliseconds and finally shows the static Heart for 500 milliseconds.


In the loop() function we fire the game() function.

In this function we show all the charters in the phrase[] variable as explained in my previous post at the #3 step. Next we blink the Heart Matrix with the function showHeart() for 10 times and after we show the Heart for 500mS

You can download the complete sketch here.

Happy Valentine’s Day 🙂
