Digital logic

A mathematical system that uses only two levels that are true (1- High) and false (0 - Low). It has various basic operators that are: AND (T· T=T), OR (F+F=F), NOT, XOR ( True when the inputs are different). NAND (is the combination between AND, NOT), NOR (is the combination between NOT, OR), XNOR (is the combination between NOT, XOR) Logic gate Logic gates are the elements that are use to create a digital circuit. It have two inputs and 1output. The low level is usually 0 volts and the high level is usually 5 volts. 

Truth table A truth table is a mathematical table, used in logic.



Integrated Circuit Integrated circuit is putting all the elements of a logic circuit in a block of silicon, living all the connections available.



LED

It is a Light Emitting Diode. When electricity passes from anode to cathode, the device lights up. LEDs can be in different colours, for example: red, green, blue, yellow and white.



Breadboard

It is a table where you put all the elements for a logic circuit to work. Also you can experiment if the circuit works well.



Breadboard jumpers

They are cables that connect different parts of a logic circuit.
