Q: What is the difference between Arduino and Raspberry Pi in IoT?

A. Arduino is a full computer that runs an operating system, while Raspberry Pi is only used to control sensors.
οΏ½B. Arduino is used for tasks requiring high processing power, while Raspberry Pi is for basic sensor control.οΏ½
C. Arduino is a microcontroller ideal for simple real-time tasks; Raspberry Pi is a microprocessor that runs an OS for complex tasks.
οΏ½D. Both Arduino and Raspberry Pi are exactly the same in terms of hardware and software.
