Electronic devices are made up of electrical components, which are the basic building blocks of an electronic circuit or system. These components control the flow of electrons in an electronic system or circuit. All circuits need to have three basic elements. These elements are a voltage source, conductive path and a load. 

Here are some basic components of electronic devices and circuits:

Diodes: Control the flow of current through specific circuits, and may also convert direct current into alternating current. Diodes are found in almost every electronic device and control the flow of electricity in electric motors and dynamos.
Transistors: One of the most important components of electronic devices, found in integrated circuits used in a variety of electronic devices such as computers, cell phones, and radios.
Capacitors: One of the most basic components used in electronics, and almost all circuits include a capacitor.
Resistors: Control the amount of current that flows through them, and control the voltage in individual components connected to them.
Semiconductors: One of the basic building blocks of all modern electronic devices, semiconductors can conduct or block electrical current.
LEDs: Light-emitting diodes are widely used in electronic circuits, included in circuits for some indication to check if the circuit is working properly.
Integrated circuits: A fundamental component in most electronic devices, the most basic circuit that is a part of a larger electronic circuit.
