Which pins should I take for I2C on Arduino Uno?
The Arduino has dedicated pins for I2C, which have built-in pull-up resistors as required by the I2C protocol. For Arduino Uno boards, these are pins A4 and A5 . Pin A4 is the SDA pin, and pin A5 is the SCL pin.
What pins are the I2C pins on the ESP32?
When using the ESP32 with Arduino IDE, the default I2C pins are GPIO 22 (SCL) and GPIO 21 (SDA) but you can configure your code to use any other pins. With I2C communication, each slave on the bus has its own address, a hexadecimal number that allows the ESP32 to communicate with each device.
What is I2C used for?
I2C, or Inter-integrated Circuit, is a communications protocol common in microcontroller-based systems, particularly for interfacing with sensors, memory devices and liquid crystal displays.
What is the I2C sensor bus?
What is the I2C Sensor Bus? The I2C bus is a simple and flexible way to transfer digital data between two electronic devices which may be physically seperate or contained on the same printed circuit board (PCB). The main processor chip on the Quadrino board communicates with the accellerometer, gyro, mag and baro sensors using this I2C bus.
What is I2C in simple terms?
I2C Controller Block Diagram. I2C (Inter-Integrated Circuit) Controller is a two-wire, bi-directional serial bus that provides simple and efficient method of data transmission over a short distance between many devices.

What do you mean by i2c?
I2C is a serial protocol for two-wire interface to connect low-speed devices like microcontrollers, EEPROMs, A/D and D/A converters, I/O interfaces and other similar peripherals in embedded systems. It was invented by Philips and now it is used by almost all major IC manufacturers.
