Q & A

What is Raspberry Pi and what does the interface mean in the context of the script?

Raspberry Pi is a small, affordable computer that can be used for various projects. In the script, the interface refers to how the Raspberry Pi connects to peripheral devices like sensors, actuators, and other components.

What is the difference between devices and peripheral devices?

Devices generally refer to any equipment connected to a computer. Peripheral devices specifically refer to equipment directly connected to the motherboard, enabling additional functionalities for the system.

What are the three types of interfaces available on Raspberry Pi?

The three types of interfaces on Raspberry Pi are I2C, Serial, and SPI. These interfaces enable communication between the Raspberry Pi and peripheral devices.

What is I2C used for in Raspberry Pi?

I2C is an interface used for interconnecting hardware modules using two lines: SDA (data line) and SCL (clock line), enabling synchronous data transfer between devices.

How does the Serial interface work on Raspberry Pi?

The Serial interface allows data transfer between the Raspberry Pi and peripheral devices using two pins: RX (receive) and TX (transmit). It is typically used for communication with serial devices.

What does SPI stand for, and how does it function?

SPI stands for Serial Peripheral Interface. It allows synchronous data transfer among peripheral devices using five pins: CS0, CS1 (for enabling/disabling devices), MISO (Master In Slave Out), MOSI (Master Out Slave In), and SCK (Serial Clock).

What are GPIO pins and their role in Raspberry Pi?

GPIO stands for General Purpose Input/Output. These pins allow the Raspberry Pi to interact with external devices like sensors, motors, and lights, and can be used for tasks like controlling actuators or reading sensor data.
