Hi all, thank you for reading my post.
I'm trying to find a circuit which will help me in my project. I need the circuit to be small (as small as possible) and sense when it is moving (not very sensitive, rather hitting an object or being moved) which will start a simple 2 minute timer once there is no further vibration, sounding a simple buzzer or speaker when the timer reaches zero.
However, I also hope that everything resets if movement starts again even if the 'alarm' is being sounded.
I will be running this off 2x 3v batteries
I can find lots of timers or vibration circuits but sadly not a hybrid like this and I have no idea how to start.
I know it's poor etiquette to have my first post here as a 'help me' post, so I apologise in advance but time sadly isn't my ally right now lol
Thank you in advance.
