Hello,
My first post
I am working on a project where a door lock will be controlled from a smart phone. The mode of communication is low power bluetooth (BT 4.0). The battery constrain is 3V (CR2032). The microcontroller will usually be sleeping except when a connection is initiated from the phone only then will it wake up and process the request and go back to sleep.
my questions?
- should I use solenoid or a low power dc/stepper motor to lock the door and unlock it?
- my main concern is power, what factors should I be looking at?
- any suggestions on low power pic microcontrollers? Is nanowatt from microchip good?
- I would be using an led for low battery status, would that affect power?
I am a software developer and have little experience with hardware but I am really interested in designing hardware, so please help me out here
