• Embedded Systems should be connected with each other to transfer data
between them. Because all operations can’t be performed on a single
system.
• For example, Arduino has 6 analog pins but NodeMCU has only one
analog pin. So two are more microcontrollers or microprocessors can be
combined to form a required embedded system.
• The connection can be established through any of the following
protocols.

I2C
UART](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

- 3. Serial Communication between NodeMCU and Arduino[Esp8266 -12E] Eng. Elaf A.Saeed Serial Communication: • Serial communication is a communication process wherein data transfer occurs by transmitting data one bit at a time in sequential order over a computer bus or a communication channel. • It is the most widely used approach to transfer information between data processing equipment and peripherals. Binary One represents a logic HIGH or 5 Volts, and zero represents a logic LOW or 0 Volts, used for communicating between the Arduino board and a computer or other devices.

- 5. Serial Communication between NodeMCU and Arduino[Esp8266 -12E] Eng. Elaf A.Saeed • All Arduino boards have at least one serial port which is also known as a UART or USART. It communicates on digital pins 0 (RX) and 1 (TX) as well as with the computer via USB. Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board).
- 6. Serial Communication between NodeMCU and Arduino[Esp8266 -12E] Eng. Elaf A.Saeed • To establish serial communication between two devices, the devices should be connected as shown below. • . Because the data sent from the device 1 should be received in the device 2 and vice versa.
