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
