 * Concepts**
 * Logic Circuits: Many devices have input conditions that control the output operation. Different conditions can be connected using AND/OR/NOT logic and then wired into electrical circuits.
 * Sensors: Some materials can release electrical charge when illuminated. This effect can be used as a light sensor that activates an electrical circuit.
 * Pixels: Pictures can be broken up into smaller elements called pixels. Even though each pixel can be a simple on-off element, lots of pixels can create realistic images.
 * Color The colors we find in nature include all the colors of the rainbow (spectral colors) and mixtures of these spectral colors. Television works by adding spectral colors together, while printers work by subtracting out spectral colors from background light.
