Communication & Protocols
Here discussed some basics of communication and list of communication protocols.
1 – Wire
1-Wire is a device communications bus system designed by Dallas Semiconductor Corp. that provides low-speed data, signaling, and power over a single conductor.
Bluetooth is a wireless technology standard for exchanging data over short distances
I2C is two wire synchronous serial communication for multi master and multi slave slave. It’s a half duplex communication.
MQTT(Message Queuing Telemetry Transport) is an ISO standard (ISO/IEC PRF 20922) publish-subscribe-based messaging protocol. It works on top of the TCP/IP protocol.
The Serial Peripheral Interface (SPI) is a synchronous serial communication interface specification used for short distance communication, primarily in embedded systems. The interface was developed by Motorola in the mid 1980s
UART (universal asynchronous receiver-transmitter) is a computer hardware device for asynchronous serial communication in which the data format and transmission speeds are configurable.
Wi-Fi or WiFi is technology for radio wireless local area networking of devices based on the IEEE 802.11 standards.

Programming Language

C Programming
C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.
