Arduino Uno

transmit

TX is short for?

TX LED

- gives visual indications whenever the Arduino is transmitting data / signals.

Main IC

- has metal legs and acts as the brain of the Arduino.

motor, button, switch

- components that uses digital pins.

RX LED

- gives visual indications whenever the Arduino is receiving data from other components.

PWM

- has the tilde (~) next to some digital pins. They act as normal digital pins but they are able to simulate analog output. - examples are the brightness that the LED will display, potentiometers.

Arduino

- is an open-source platform used for building electronic projects.

Voltage Regulator

- is not something you can interact with on the Arduino. - controls the amount of voltage/signal from the outside power source.

Power LED indicator

- lights up whenever you plug your Arduino into a power source.

open-source

- means that it has no license, giving the freedom to the user to create and modify his desired program.

AREF

- most of the time, you can leave this pin alone. It's sometime used to set an external reference voltage (between 0-5V) as the upper limit for analog input pins.

Uno

- one of the more popular boards in the Arduino family and is a great choice for beginners.

3.3V

- pin that supplies 3.3 volts of power.

5V

- pin that supplies 5 volts of power.

Analog

- pins that can read signals from analog sensors such as temperature sensors, and converts it to a digital value to be readable.

Digital

- pins used for both digital input (button) and output (LED).

Reset Button

- pushing this will temporarily restart the program/code without the need of restarting your computer.

GND

- short for "Ground". There are several of these kinds of pins on the Arduino that is used to ground your circuit.

Power Barrel Jack

- where a power source such as a wall power supply is connected.

Power USB

- where you connect a USB cable coming from your computer that acts as a power source. - also used when uploading data to your Arduino Uno.
