Simple electronic project. I need everything to be in nano size, as small as possible.
I need a tilt switch/sensor and when it is activated for the time and date to be logged. MicroSD to hold the log.
Real Time Clock to keep the time.
Thats it. I don't need recharging or any other functionality. I don't need any LEDs or an on off switch.
Power source : 3.7v Lipo or Coin Battery
I would like everything to be done, so I can send off to buy parts and pcb board. All coding and everything must be complete, so all I need to do is solder the commonest to the PCB board and it works,
