The goal of this design was to address an existing product and develop a new interface that improves the user experience and adds value for the consumer.
Arduino is an open-source electronics prototyping platform used to create interactive objects and environments.
New components added to the improve interface include a battery fuel gauge, an Arduino Pro Mini microcontroller, push button and three LEDs.
One improvement: battery power indication LEDs. A push button is used to activate the LEDs indicating the life of the battery. (Green = greater than 50%, Yellow = equal to or less than 50%, Red = less than 25%)
Another improvement: twisting open to power on and twisting close to power down.
