Clear heart

thingiverse

The project was created specifically for kids' holiday celebrations. A key feature is that each child starts with a blank heart, devoid of LEDs, and as they perform kind acts during the game, they earn LEDs to light up their heart. Installing it in a toy is a breeze - simply reverse the polarity if it doesn't illuminate, and swap the LED connections. As the kids do good deeds, everyone's heart begins to shine! It's truly fantastic!
