=How can i create a device that provides a problem solution, based on a digital logic?=

Definitions:
Digital logic: Digital logic uses just two symbols 1 and 0, 1 will be true and 0 will be false. These symbols can be equated with others. Using this type of logic there can only be 2 statements or conditions, true or false. It makes possible to design and build circuits that will remain indefinitely in one state unless and until they are switched to the other state.

Logic gate: A logic gate is an elementary building block of a digital circuit. They usually have 2 inputs and one output. These are the different types of logic gates: AND, OR, XOR, NOT, NAND, NOR, and NXOR.

Truth table: A truth table shows the function of a logic gate. it shows the output state for every combination of the input states.

Integrated circuit: An integrated circuit is an electronic circuit manufactured over a thin substrate of semiconductor material. Metals are atached to create the connections between different semi conductor devices or any electronic device.



Led: A led is a semiconductor light source. It is used in many electronic devices nowadays like alarm clocks, cell phones, remote controls, among others. They are diodes that have a special semiconductor which makes light.



Breadboard:It´s a construction base to make electronic circuits.It doesn´t need soldering so it is reusable. Some of them use soldering but they aren´t as usefull. Breadboard jumpers: The bread board jumpers are wires that can be attached to a breadboard and they are used to make electronic circuits.

Logic Gates:
