 [Direct current (DC)](https://en.wikipedia.org/wiki/Direct_current) specifies a unidirectional flow of electrons; that is they flow in one direction only.
 
 The simple nature of direct current lends itself well to creating digital logic circuits, because it can represent binary `1` when `ON` (within a given voltage range), and binary `0` when `OFF` (at ground, or `0V`). It's also the type of current that batteries generate.

 Because DC is used as the primary type of current in digital logic circuits, most of this tutorial will focus on DC circuits.
 
 Direct curent is also used in [long distance, high power, electrical transmission lines](https://en.wikipedia.org/wiki/High-voltage_direct_current) (usually `>250kV`) because of lower electrical losses.
 
 Meadow provides two _power rails_ that supply `5V` and `3.3V` direct current. The `3.3V` rail can be found on the left header, and the `5V` rail can be found on the right header:

-CMOS is the technology that nearly all modern integrated circuits use. CMOS `HIGH` signals can vary but they're defined as the `V`<sub>`DD`</sub> level, which is usually `3.3V` in most common circuits. In fact, for nearly all circuits we'll create, we'll use the CMOS standard with `V`<sub>`DD`</sub> = `3.3V` as the upper end of the voltage supply source.

 Internally, most microcontrollers, CPUs, and other complex chips use a lower `V`<sub>`DD`</sub>, often `1.8V` or less, which allows them to operate at faster speeds. However, most microcontrollers use `3.3V` on their IO pins.
