I²C – Inter-Integrated Circuit

I²C or I2C is an abbreviation of Inter-Integrated Circuit, a serial communication protocol made by Philips Semiconductor (now it is NXP Semiconductor). It is created with an intention of communication between chips reside on the same Printed Circuit Board (PCB). It is commonly usually used to interface slow speed ICs to a microprocessor or a microcontroller. It is a master-slave protocol, usually a processor or microcontroller is the master and other chips like RTC, Temperature Sensor, EEPROM will be the...

HC-05 Bluetooth Module

HC-05 Serial Bluetooth Module

Bluetooth is a technology for wireless communication. It is designed to replace cable connections.It uses serial communication to communicate with devices. It communicates with microcontroller using serial port (USART). Usually, it connects small devices like mobile phones, PDAs and TVs using a short-range wireless connection to exchange documents. It uses the 2.45GHz frequency band. The connection can be point-to-point or multi-point where the maximum range is 10 meters. The transfer rate of the data is 1Mbps. HC-05 Bluetooth module provides switching mode...

SPI Communication

SPI – Serial Peripheral Interface

SPI (Serial Peripheral Interface) is a full duplex synchronous serial communication interface used for short distance communications. It is usually used for communication between different modules in a same device or PCB. SPI devices communicates each other using a master slave architecture with a single master. Multiple slaves are supported through individual slave select lines. SPI Interface SPI is called as a 4-wire bus as it requires four wires for its communication as shown below. In the case of single slave communications...
