I would like to build a pressure activated 'mushroom'. When kids go and sit on the mushroom, it should play a predefined tune (e.g. the only track on the SD card) but when kids leave the mushroom, it should either stop playing or fade out the current mp3. When kids go and sit on the mushroom the entire show starts from scratch.
Now since these mushrooms will be placed in the playground; i have the following questions:
1) Is this the cheapest way to do this?
2) Is this the most power friendly way to do this (e.g. by supplying a 2000mAh battery, how long will it last?
3) Can i use an pressure pad attached to a trigger to accomodate my wishes?
I am a programmer by nature, but haven't done anything with Arduino before...
No public wish lists :(
