Design a long-life battery powered circuit, connected to the following external parts:
an Arduino Pro Mini 5V 16MHz.
a HC-06 bluetooth module.
an A3144 hall effect sensor.
a 3 pin switch.
a DC motor, preferably running at 9V.
a suggested 6 pcs 1.5 V Energizer Ultimate Lithium AA batteries.
The Arduino will have a power down function. It can sleep-wakeup-sleep for weeks when it’s not paired over the bluetooth.
The switch as well as the hall effect sensor can be in either of their states (“ON” or “OFF”) for weeks, during which time they shouldn’t drain the batteries. They should only use energy when the microcontroller is checking their status.
The DC motor will only run for a few times a week during a few seconds. It should run on about 9V.
I need your help to design a complete working circuit with components etc. (not modules) in Fritzing or similar, which I will solder on a prototype board after testing on breadboard.
In the future, I want to change to a 3.3V Pro Mini and Bluetooth LE and hopefully get the device working for years without battery change.
