“Donation boxes can be much more interesting and attractive when you combine them with electronics and a little bit of programming. This instructable will show you how to. As the name explains, making donation boxes interactive can help you gain much more attention and make people happy at the same time! Indeed, and awesome way to set up a charity and help the needed ones by installing it in shopping complexes and other public places (if a bigger version of the same is made). This was just a prototype to present the basic idea which when modified and used at a bigger level, can definitely help. The following project uses an arduino for all it’s processing. The RGB LEDs installed inside the box keep on flashing and changing colors which can attract much attention. When a person donates a coin, the ultrasonic sensor installed just on the box detects that and the servo present at the top waves 2-3 times with a ‘Thank You’ message displayed. This feature can surely bring a smile on the person’s face who just donated that coin! Using only arduino and some other basic parts, you can make this project within 3-4 hours max. without the need of hunting the parts. Although a bigger version of the same would be much better, but that doesn’t mean that this small one is useless. Even this one can be put at various places.”
