Sensors and Actuators
To interact with any embedded systems we need inputs. The input may be provided by the user or by any sensor. Sometimes some systems need more inputs or outputs. So the processor selection will be based on I/O
Power Supply
Aplication Specific circuit
The key component to provide the power to the embedded system circuit. Usually the ES requires 5V supply or can be range from 1.8V to 3.3V. The power supply source can be a battery or can be provided by a wall adaptor. It is selected as per user requirements and application requirements.
Sensores
Some hardware components are common while designing the embedded systems. But some are different and depends on the application need. Like a temperature sensor need a temperature sensor for sensing the temperature.
LoRA
Processor
It acts as the brain of the system. Is responsible for deciding the performance of the embedded system. It can be an 8, 16 and 32 bit processor.
Memory
The memory is available on-chip. We generally talk about
two types of memory in the
embedded systems.
Memoria Flash, SRAM y EEPROM
Actuators
Parts required for our ES
electrovalve
Serial Port
Is a serial communication interface which information transfer in or out one bit at a time.
Communication Port
Is the type of interfacethat is used to communicate with other types of embedded systems. In the embedded system there is a multiple types of communication ports like UART, USB, Ethernet, RS-485 and many more

What is an embedded system? An embedded system is a microprocessor-based computer hardware system with software that is designed to perform a dedicated function, either as an independent system or as a part of a large system. At the core is an integrated circuit designed to carry out computation for real-time operations
Timer
There is always a requirement of delay that needed to provide in the application.
timer-0 is 8 bits, Timer-1 is 16 bits and Timer-2 is 8 bits.
