tell me about a breadboard
breadboard is a device that is used to build temporary circuits.
Breadboards are available in small or large sizes.
They consist of holes, which are connected in certain configurations, in which components can be placed and connected.
Since the components can easily be moved or replaced, they are typically used for prototyping and testing new circuits

what is an arduino
An Arduino is an open-source microcontroller development board
This means that the Arduino can be used to read sensors and control things like motors and lights.
This allows you to upload programs to this board, which can interact with things in the real world.
How Arduinos work
Written code can be uploaded from a computer to the Arduino through a cable connected to port (A).
After the Arduino code has been uploaded and the Arduino is disconnected from the computer, a power cable is inserted at the other port (B).
Once the Arduino is powered, it will continuously loop through the circuit until either power is cut or it is switched off

Arduino Advantages
Easy to use
The IDE (Integrated Development Environment: the place where the actual coding takes place) has a simple, yet highly effective layout, with ready-made code examples for new coders to use as a basis to start with and help novice coders to understand more about coding an Arduino
Helpful community
The Arduino community is worldwide and provides thousands of resources online.There are also many YouTube channels to make learning Arduino easier.
Cheaper than other microcontrollers
it is relatively cheap compared to other microcontrollers
Used in industry
tell me about scratch
Scratch was the first block coding language that was developed by MIT. This language was created as an easy and simple way for learning how to code, i.e., for giving basic information to a computer in the form of block codes
disadvantages of arduinos
Limited in what it can do
Slower than script coding
