Electronics

1. voltage

   • potential difference in charge between two points in an electrical field

2. resistance

   • opposition that a substance offers to the flow of electric current

3. Ohm's law

   • mathematical relationship among electric current, resistance and voltage.

4. LED (Light-emitting diode)

   • semiconductor device that emits light when an electric current is passes through it
     • positive
       • anode
     • negative
       • cathode

5. arduino

   • Open-source electronics platform based on easy-to-use hardware and software.
   • Arduino Leonardo

6. circuit

   • A path between two or more points along which an electrical current can be carried.

7. some components of the arduino leonardo are

   • USB power supply
   • Additional power supply
   • power pins
   • microprocesor

8. protoboard

   • A board that has small holes were components may be attached without solder, used for the temporary construction of circuits.
