Charging circuit for single-cell (3.7V) Lithium-Polymer batteries.
Some of the sew tabs on the LilyPad USB Plus have special functionality:
An 'A' in front of the number denotes a tab that can function as an
sensors that output a varying voltage like the light sensor built into the ProtoSnap Plus.
A '~' symbol in front of the number indicates that tab supports
PWM (Pulse Width Modulation) output
.
These tabs can output an "analog" signal that can be used to vary the brightness on LEDs, etc.
Note: The "A" in front of analog sew tab numbers in your code is optional. However, do not include the "~"
symbol for PWM outputs. It is only provided to make it easy for you to check which pins can produce PWM
(analog) output and is not used in programming.
Below is a table that lists the components connected to the LilyPad USB Plus sew tabs.
