With the SLEEP example the Power LED turns off when the SLEEP command is being executed because the
EEPROM is inactive. Current consumption is 10 mA while the loop is being executed but drops to 40 µA during
the SLEEP command.

Precautions
Be alert to static sensitive devices and static-prone situations. The BASIC Stamp, like other integrated circuits,
can be damaged by static discharge that commonly occurs touching grounded surfaces or other conductors.
Environmental conditions (humidity changes, wind, static prone surfaces, etc) play a major role in the presence of
random static charges. It is always recommended to use grounding straps and anti-static or static dissipative
mats when handling devices like the BASIC Stamp. Since you don’t have a dissipative mat, touch a grounded
surface after you have approached your work area. This isn’t as critical as you might think but being prudent only
protects your hardware.
Before building circuits, disconnect the battery.
