CONNECTING LED TO A BREADBOARD
                  A breadboard is a tool used to build and test circuits without soldering. It has rows and columns
                  of tiny holes connected internally, making prototyping easier.

                  Steps to Connect an LED to a Breadboard:

                  Step  1    Insert an LED into the breadboard.
                  Step  2    Connect a 330Ω resistor to the anode (+) leg of the LED.

                  Step  3    Use a jumper wire to connect the resistor to an Arduino digital pin 13.

                  Step  4    Connect the cathode (-) leg of the LED to the ground (GND) on Arduino.


















                     Checkpoints:
                     The LED is placed correctly on the breadboard.

                     A resistor is connected to prevent excessive current flow.


                  WRITING AND UPLOADING A BASIC SKETCH

                  Now that we have designed our circuit, we need to program the Arduino to control the LEDs.
