Linked list is a data structure where elements are stored in nodes with pointers to the next node. Array list is a dynamic array that can grow or shrink in size.

• Linked list allows for efficient insertion and deletion of elements anywhere in the list.

• Array list provides fast access to elements using index, but slower insertion and deletion compared to linked list.

• Example: Linked list - 1 -> 2 -> 3 -> 4 -> 5, Array list

Selecting components involves assessing specifications, compatibility, reliability, and cost-effectiveness for optimal design performance.

• Specifications: Ensure the component meets voltage, current, and frequency requirements (e.g., choosing a microcontroller with adequate GPIO pins).

• Compatibility: Check if the component integrates well with other parts of the design (e.g., Op-amps that match the microcontroller's ADC ...read more

An OpAmp circuit amplifies voltage signals using resistors, capacitors, and the operational amplifier itself.

• OpAmp: The core component that amplifies the input voltage difference.

• Resistors: Used to set gain and feedback in configurations like inverting and non-inverting.

• Capacitors: Can be used for filtering or stability in frequency response.

• Power Supply: Provides the necessary voltage levels for the OpAmp to operate.
