A lil' history ...
This project involved the building of "MINI-VOLT", an R/C Battery
Voltage Monitor using the PICAXE microcontroller. This gadget also is
capable of recording 240 voltage samples, from rates ranging from two sample per
second (2 minutes total), to two samples per minute (120 minutes total). After
collecting its required samples, the use can hook up "Mini-Volt" to its
programming/download cable and read the samples, whereas you can then plot the
recorded voltage data. An integrated Low-Voltage Alarm (LVA) is also
included in the design and notifies the user when approaching low voltage levels
by flashing a bright LED and/or by stuttering the ESC.
