ARDUINO UNO MICROCONTROLLER

Barrel Jack

It can be used with either a 9V or 12V supply.

USB Port

It provides power and communicates with the board when plugged into a computer via USB.

RX

It blinks when receiving data.

TX

It blinks when transmitting data.

LED Troubleshooting

It blinks when the program is running properly.

Digital, Analog, and Ground Pins

It can be used for input, output, power, and ground.

LED On/Off

It indicates if there is a power

Reset Button

It manually resets the Arduino that makes your code restart

Breadboard

is used to create circuits and connect different sensors and actuators to the Arduino board, it is also called a solderless breadboard

Positive 1-30

is used to connect the horizontal pins which is called power rails. The connection on the blue line rail is different from the red line rail.

A1, B1, C1, D1, E1

is used to connect the vertical pins

Trench

serves a very important purpose, if a dual in-line package or DIP chip is used, there is a separation of connection is made so that if connection is made to each side of the IC there will be no interference between the functionality of the leg on the opposite side.

Light Emitting Diode

is a semiconductor diode that converts electric energy into electromagnetic radiation at a visible and near infrared frequencies when its pn junction is forward biased

Parallel Circuit Connection

It is an electrical connection that has two or more paths for the current to flow in which the loads are parallel to each other.

Series Circuit

It is an electrical connection that is connected along a single path where the current flows in the same direction.

Switch Circuit Connection

It is an electrical connection which is installed on one path that allows or disallows the flow of current to a device from the source.
