Task 1: Breadboards

What is a Breadboard?

A breadboard is a tool used to build and test circuit without the need for soldering . It’s great for experimenting because you can easily change components and try different circuit designs.

Parts of a Breadboard:

1. Terminal Strips (Rows and Columns) These are the main area of the breadboard. They have lots of holes in rows and columns where you insert electronic components (like resistors, LEDs, and wires). Each column is electrically connected inside the breadboard. This means if you plug one end of a resistor into one hole in a column, anything else plugged into the same column will connect to the resistor.

2. Power Rails These are typically on the sides of the breadboard and are used for power connections. Each row on a bus strip is connected internally, allowing you to power multiple components easily.

3. Divider There’s usually a central divider that separates one half of the terminal strips from the other, with no electrical connection between them. This helps in organizing complex circuits or adding different sections of a project.

Arduino UNO Pinout:

The Arduino UNO has a set of pins that you can use to connect things like LEDs, sensors, and buttons. It has 14 digital pins (numbered 0 to 13) that can be used to turn things on or off, like an LED. Some of these can also create fading effects using something called PWM. There are 6 analog input pins (A0 to A5) that can read values from sensors like light or temperature sensors. You also have power pins to give power to your components, including 5V, 3.3V, and GND (ground). Pin 13 is special because it’s connected to a built-in LED on the board. Pins 0 and 1 are used for talking to the computer (serial communication). All these pins help your Arduino "talk" to other parts of your project.
