Q1. How to use a sensor with a microcontroller board(any board arduino, pico, esp32) how does the board take reading from the sensor and how does board controls the sensor(include io port, adc and others)

Ans.

A microcontroller board can interface with a sensor by connecting it to the appropriate input/output ports and using the board's built-in functions to read data from the sensor.

Connect the sensor to the microcontroller board using the appropriate pins or ports.
Configure the board's input/output ports to communicate with the sensor.
Use the board's analog-to-digital converter (ADC) to convert analog sensor readings into digital values.
Read data from the sensor using the board's...read more

Q2. Difference between microprocessor and microcontroller

Ans.

Microprocessors and microcontrollers are both integrated circuits used in electronic devices, but they differ in terms of functionality and architecture.

Microprocessors are general-purpose processors used in computers and other complex systems, while microcontrollers are specialized processors used in embedded systems.
Microprocessors typically have separate memory and I/O interfaces, while microcontrollers have integrated memory, I/O ports, and peripherals.
