Q3 CT 10 - Electricity & Arduino

Resistor

* A device which limits the flow of a current in a circuit.

Microprocessor

* A processing device that converts data into information based on some sets of instructions.

Microcontroller

* An electronic system which consists of a processing element, a small memory (RAM, ROM, EPROM), I/O ports, etc. on a single chip.

Microprocessor

* It is a very compact electronic chip due to which it is referred to as the microprocessor.

Amperes

* The unit of current

Current

* When an electrons move from negative terminal to positive terminal of a battery, they give rise to current.

Resistance

* a measure of the difficulty of passing an electric current through that substance.

Current

* the amount of electric charge that flows when one coulomb of charge moves past a point in one second

Current

* the direction in which the current flow is the opposite to the direction of the electrons

Coulomb

* the measuring unit of charge

Power LED

- Indicates that the Arduino Board is receiving power.

Atmega 328 Microcontroller

- The heart of your Board

TX & RX LED

- These LEDs indicate communication between Arduino and computer.

Power Pins

- Use these pins to provide +5V and ground to your circuit.

Digital Pins

- Use these pins with digitalRead(), digitalWrite(), and analogWrite()

Analog Pins

- Use this pins with analogRead()

USB Port

- Used for powering your Arduino Uno, uploading your sketches to the Arduino, and for communicating with your computer.

Built in LED

- connected to Pin 13

Reset buttons

- resets the ATmega microcontroller

Current Electricity

A flow of charged particles, such as electrons or ions, moving through an electrical conductor or space.

Static Electricity

A form of electricity resulting from the imbalance between positive and negative charges within a material that occurs when electrons move from one material to another.

Current

A rate of flow of charge

Electricity

A type of energy that can be built up in one place or flow from one place to another.

Extension Wires & Adaptors

Examples of Alternating Currents

batteries

Examples of Direct Current

Current Electricity

It is defined as the net rate of flow of electric charge through a surface.

Alessandro Volta

Person behind voltage

Static Electricity

When electricity gathers in one place

Current Electricity

When it moves from one place to another

Voltage

a difference in electric potential between two points

Electrons

the negatively charged particles in an atom
