![]() Low = substitution is possible with little or no economic and/or performance impact Medium = substitution is possible but there may be an economic and/or performance impact High = substitution not possible or very difficult. The availability of suitable substitutes for a given commodity. A higher recycling rate may reduce risk to supply. The percentage of a commodity which is recycled. The number of atoms of the element per 1 million atoms of the Earth’s crust. This is calculated by combining the scores for crustal abundance, reserve distribution, production concentration, substitutability, recycling rate and political stability scores. The Chemical Abstracts Service registry number is a unique identifier of a particular chemical, designed to prevent confusion arising from different languages and naming systems.ĭata for this section been provided by the British Geological Survey.Īn integrated supply risk index from 1 (very low risk) to 10 (very high risk). Where more than one isotope exists, the value given is the abundance weighted average.Ītoms of the same element with different numbers of neutrons. This is approximately the sum of the number of protons and neutrons in the nucleus. The mass of an atom relative to that of carbon-12. The transition of a substance directly from the solid to the gas phase without passing through a liquid phase.ĭensity is the mass of a substance that would fill 1 cm 3 at room temperature. The temperature at which the liquid–gas phase change occurs. The temperature at which the solid–liquid phase change occurs. The arrangements of electrons above the last (closed shell) noble gas. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f). The atomic number of each element increases by one, reading from left to right.Įlements are organised into blocks by the orbital type in which the outer electrons are found. Members of a group typically have similar properties and electron configurations in their outer shell.Ī horizontal row in the periodic table. Note: If you don't have experience with Arduino or don't know how to install libraries you can check this site.A vertical column in the periodic table. the time is 08:08:08 #define HMoverlap CRGB::Cyan #define MSoverlap CRGB::Yellow #define SHoverlap CRGB::Purple There's also the option to customize the overlapping colors, these colors are displayed if there's an overlap between hours, minutes and seconds. Where each number represents the RGB value, in this case Red=255, Green=0, Blue=0 These values can also be edited with custom RGB values such as: #define secondColor CRGB(255,0,0) You can also customize the color of the LED's by editing this line: #define hourColor CRGB::Blue #define minuteColor CRGB::Green #define secondColor CRGB::Red To customize your date and time setting, go to void setup and edit this line: RTC.adjust(DateTime(Year, Month, Day, Hour, Minute, Second)) Īfter you upload the code, the RTC will start from the defined date and time. ![]() The FastLED Library for Arduino can be downloaded here: Īnd the RTClib can be found here: Customization We'll be using the FastLED Library for the addressable LEDs along with Wire.h and RTClib.h to control the RealTimeClock.
