The basis of digital electronics is based on the Boolean algebra. The logical functions directly from the Boolean algebra are the basic tools of digital electronics. They are implemented in electronics in the form of logic gates. When talking about logic circuits, the two main families are TTL (Transistor-Transistor Logic) and CMOS (Complementary Metal-Oxide-Semiconductor).

Hot air welding allows the welding of surface components which are very small or whose legs are inaccessible with a soldering iron. The first element to take into account is the choice of the tool for heating the dough. It is possible to do this type of maneuver with a hot air gun or a reflow oven.

A new way to make printed circuit boards is to use EasyEDA (https://easyeda.com). EasyEDA makes it possible to make diagrams, simulations and printed circuits and all that from their website or the application for the Internet browser Chrome. In less than 2 hours of work (for an inexperienced person), it is possible to switch from a simple idea in PCB manufacture to circuit design and simulations.

Stepper motors are motors that allow you to execute movements with high precision. They are mainly found in printers, CNCs (computer numerical control) and other devices that require good precision. The main disadvantage of these motors stems from their speed, in fact, the more their precision is increased and their speed decreases.
