Presentation raspberry pi
Marco Casini presents the Raspberry Pi 2, a credit card-sized computer designed for education, featuring a 4-core CPU and various connectivity options like USB, HDMI, and GPIO. It highlights the versatility of GPIO pins for input/output tasks and discusses programming it using Python and shell scripting. Casini also demonstrates a practical example of a motion detection alarm system utilizing the GPIO capabilities.

- 1. HELLOI am MarcoCasini I am here to present Raspberry Pi 2 You can find me at: https://it.linkedin.com/in/marcocasini2 1 !
- 2. OVERVIEW Let’s start withthe first set of slides on the first credit card that goes over the wallet!
- 3. WHAT IS RAPSBERR Y PI? •A credit card sized PC • Plugs into a Tv or Monitor • Very Cheap ~ 30£ each • Over 5 milion units sold • Uses Broadcom BCM2836 4core CPU • Designed for education
- 4. A little bit deeper.. -1 GB RAM - 4 USB - Ethernet - SD ROM - HDMI - GPIO - CAMERA - 3.3v VOLTAGE

- 6. Arduino Raspberry Pi MicrocontrollerJust a tiny Pc FLASH ROM Operating system Special Purpose General Purpose One job at a time Multitasking Hardware minimal Normal Hardware

- 9. GPIO - general purposeinput/output A more accurate vision on this powerfull port
- 10. GPIO – Pins Physicalinterface between the Pi and the outside world. 40 pins, 26 are GPIO pins 14 are for power or ground
- 11. Input Signals incoming from sensors GPIO – Input /Output Output Sending signalsto ouput, led or whatever.
- 12. GPIO - OUTPUT GPIO asan output, use HIGH or LOW in computing terms to send values. HIGH 3.3V LOW 0V LED -GND,+3.3V
- 13. GPIO – INPUT INPUT, listeningvalues OUTPUT, no standardized, it depends on the nature of the connected device
- 14. GPIO & PYTHON 1)For usingpython we must install it using pip, the package manager : 2) We need to install python now 3)For control GPIO we need 2 libraries distribute e RPi.GPIO:
- 15. GPIO – SHELL SCRIPTING Shell Script– Native on Linux ! Supported languages: C, C++, JavaScript, HTML,Python
- 16.
- 17. MOTION DETECTIO N ALARM IN to VCC OUTto GPIO4 GND to GND. MOTION DETECTION HIGH GPIO4
