  Introduction to microcontrollers and electronics

   

  

  Basic Electronics

   

  Electricity is the movement of electrons. Electrons create charge, which we can harness to do work. Your light-bulb, your stereo, your phone, etc., are all harnessing the movement of the electrons in order to do work. They all operate using the same basic power source: the movement of electrons.

  There are three basic principles to electricity

  • Voltage is the difference in charge between two points. (The pressure)
  • Current is the rate at which charge is flowing.  (Flow)
  • Resistance is a material’s tendency to resist the flow of charge (current).
  
  

   

  Basic Electrical Components

  Battery - converts chemical energy into electricity

  Resistors - Resists the flow of electricity

  Capacitors - Stores electrons in an electric field

  Inductors - Stores electrons in a magnetic field

  Diodes - Only allows electrons to flow in one direction
