It is not easy to explain the meaning of a board like Raspberry Pi for nerds, geeks, coders and anyone involved in technology. On one side, Raspberry Pi is a mini computer and the size substantially changes all possibilities. A mini computer could be placed in a car dashboard or integrated into a kitchen appliance. A mini computer has also minimum power requirements. You can use it with batteries. On the other side, Raspberry Pi has input and output pins capable of being used to connect devices. What kind of devices? A camera but also micro Oled screens, biometric finger print readers, relays to turn on and off big appliances, lights, temperature sensors, RFID card readers and lots more. If there is anything the price. A Raspberry Pi while I write this book costs $35 for model 3 and $10 for Pico version. So possibilities are virtually endless.This book was written under the premise of "learn by doing" and it includes chapters for beginners and also interesting electronics and coding project advanced readers.Book contentsHistoryInstallationRequirementsLinux command lineGraphic interfacePython codingProject 1: Led control and button readingProject 2: Bitcoin buy alertProject 3: Smartphone controlled robotProject 4: QR controlled barrierProject 5: Anti Covid assistance contrlProject 6: Employee clock with RFID cardsProject 7: Photo boothProject 8: Game consoleAll projects includes easy to find parts, complete circuits, complete Python code and details.
