Designing battery indicator

[archerindigo]

With the new flow decided after #1 , we need to add battery level indicator to let players know when the battery is fully be charged.

Since there might be difficulties to embed any power electronics into the battery, the battery level should be provided by the electric box and the charging station. They can detect existence of the battery and show its battery level. (pseudo level, simply based on how many seconds the battery is placed into the charging station)

Possible indicator designs:

• LED array consist or 4 bulbs. Initially only 1 bulb is flashing to indicate low-battery. When fully charged, all 4 bulbs are on continuously
• LCD (16x2) showing a battery level bar

Questions:

• Which one is more suitable?
• Where to install the indicator in the electric box and the charging station

Update: 1602 LCDs are preferred as it is more appealing and we could source 2 LCDs from the lab yesterday.

We're now using 1602/2004 LCD display as battery level indicator.

Implementation continues in #34
