Aim of the Experiment

The objective of this experiment is to interface an LED with a Raspberry Pi and develop a Python program that controls the LED's state. Specifically, the program will turn the LED ON for a duration of 1 second, followed by turning it OFF for 2 seconds, repeating this cycle indefinitely. This task will help in understanding the basic functionality of the General Purpose Input/Output (GPIO) pins on the Raspberry Pi and how to control external hardware via programming.

This experiment demonstrates the core concepts of interfacing with GPIO pins and controlling external devices. The skills learned here are applicable to various real-world applications, such as:

1. Basic Indicator Systems:

   • LEDs are commonly used to indicate the status of a device, such as showing whether a system is powered on or functioning correctly.
   • Example: An LED indicator to signal when a device is in standby or operating mode.

2. Embedded Systems Development:

   • Understanding GPIO pin control is fundamental for developing embedded systems where devices interact with sensors, actuators, and displays.
   • Example: A microcontroller-based alarm system that uses LEDs to signal alerts.

3. Home Automation:

   • GPIO pins can control LEDs in smart home projects, such as controlling lights remotely or creating feedback loops for system status.
   • Example: An automated lighting system that turns lights ON/OFF based on sensor data.

4. Internet of Things (IoT) Projects:

   • Interfacing LEDs with Raspberry Pi enables basic feedback systems, which are often used in IoT devices that monitor and display data.
   • Example: A smart sensor system with LED indicators to show environmental conditions like temperature or humidity levels.

5. Prototyping for Consumer Electronics:

   • LEDs are frequently used in the prototyping phase of new electronic devices, helping developers quickly test and visualize circuit designs.
   • Example: Prototyping a new handheld device with visual feedback via LEDs.
