Hello Fellow Arduino Enthusiasts!
I'm only a month into working with an arduino uno/raspberry pi and this is my first post. I just want to first thank you all for taking your time to add to the convo.
I successfully programmed an FSR to gradually cycle through colors of an RGB led depending on the amount of pressure applied. Having learned how to do that, I want to push the utility of the FSR and turn in into a sort of simple "security device." The idea is: I place an object (wallet) on top of the sensor, and once that object is removed, the arduino sends a signal to an external device such as phone or tablet.
Sounds simple on paper, but I'm stuck trying to figure out a way to establish that sort of inter-connectivity. I figure I would need to purchase a bluetooth device for my breadboard as a start, but after that....?
Sorry if all this seems trivial, but I'd greatly appreciate any feedback. Thanks!
