The Raspberry Pi 's GPIO pins provide a powerful way to control external hardware, such as LEDs, sensors, and motors, and receive data from these devices. In this project, you will learn how to:

1. How to configure a Raspberry Pi for GPIO use.
2. How to connect hardware to the Raspberry Pi using the included kit.
3. How to write simple Python programs in the Thonny IDE.

If your Raspberry Pi isn't set up yet, you can install the operating system using Raspberry Pi Imager :

1. Download the Raspberry Pi Imager from raspberry pi.com.
2. Insert the microSD card into your computer.
3. Launch Raspberry Pi Imager and choose:
   • Select Model: Raspberry pi (your model)
   • Choose OS : Raspberry Pi OS (64-bit).
   • Select Storage : Select the microSD card.
4. Click Write and wait for the process to complete.
5. Insert the MicroSD card into the Raspberry Pi and connect all cables.

After booting the Raspberry Pi :

Open the LXTerminal :

1. Go to Interface Options and enable the following features:
   1. I2C : For devices such as the LCD module.
   2. SPI : For sensors and other modules.
   3. 1-Wire : For the DS18B20 temperature sensor.
2. Save the changes and reboot the Raspberry

1. Open Thonny :
   • Click on the Raspberry Pi menu > Programming > Thonny Python IDE .
2. Writing a script :
   • Click on New File .
   • Enter a simple print command such as:

• Click Save and choose a name like test.py .

1. To run the script :
   • Click the green Run button (▶).

The Raspberry Pi has 40 GPIO pins that you can use for input and output. Here is a list of the most commonly used pins:

The GPIO Kit contains a wide range of components that will allow you to perform various electronics and programming projects. Here is an overview:

What's in the GPIO Kit?

The GPIO Kit contains a wide range of components that will allow you to perform various electronics and programming projects. Here is an overview:

1. Breadboard : Useful for building simple circuits without soldering.
2. Jumper wires : Wires to connect components to the breadboard and the Raspberry Pi .
3. LEDs : Visual signals; including an RGB LED to create colors.
4. Resistors : For limiting current in circuits and protecting components.
5. Pushbuttons : For use as input devices in circuits.
6. LDR (light sensor) : Sensor that measures light intensity.
7. Potentiometer : Variable resistor that can be used for various applications.
8. Passive piezo buzzer : Sound source for creating tones or signals.
9. Ultrasonic Distance Sensor (HC-SR04) : Measure the distance between the sensor and an object using ultrasonic sound.
10. 2-Digit 7-segment display : For easy display of numbers.
11. IR Remote Kit: For infrared wireless communication, such as remote controls.
12. LM393 Sound Sensor : Measures sound intensity in the environment.
13. Touch Sensor: Measures touches and can replace a push button.
14. 4x4 Keypad : For easy entry of numbers and codes.
15. Tilt Sensor (SW-520D) : Detects tilts or movements.
16. 40-pin male/male header : For expanding and customizing your project.
17. DS18B20 Temperature Sensor : Precision sensor for temperature measurements.
18. Servo and stepper motor: Suitable for performing precise movements and rotations.
19. 16x2 LCD display (I2C) : For displaying text or data, such as sensor values.

How does the breadboard work?

• Horizontal rows are connected in the middle (for components).
• Vertical rows (on the side) are usually for power and ground.
