Get rich quick with this interactive piggy bank! Alex Pikkert designed a money saving machine that swallows your coins and thanks your for saving. When you slide a coin down the ramp, the coin covers a light sensor, kicking off the following interaction: a servo opens a door below the ramp and a cam mechanism powered by the DC motor pushes the coin into a recess below the door. This all happens quite seamlessly! Meanwhile, an animated graphic powered by a second servo thanks you for saving while the mp3 player sounds a musical money track. A nice incentive indeed!

We also love that Alex used a grey bitSnap to secure the speaker down at the end of the his circuit!
