Standby Mode

[laurb9]

Normal (motors off) power consumption is about 15mA.

Standby Mode should

• turn off motors (drive nSLEEP LOW)
• turn off display (this is impossible with current wiring) - maybe power display from a high current pin or ?
• put uC to sleep, wake up via button interrupt

Another way to achieve all this is to use one of these for a little extra cost:

About turning off motors see comment in #64

New versions might not need display at all. The MPU should be powered off though if not needed.
The app keeps all the info though, so maybe a power button is all we need.
