In our previous tutorial learned about SPI communication in Arduino. Today we will learn about another Serial Communication Protocol: I2C (Inter Integrated Circuits). Comparing I2C with SPI, I2C has ...

 Arduino Mega ...

Two power pins, one interrupt pin, and two I2C pins. The pinout of the module is as follows: VCC - Provides power for the module, Connect to the 5V pin of the Arduino. GND - Ground Connected to Ground ...

The Arduino Nano is powered by an Atmel ATmega328 ... There are also two SPI controllers and two I2C controllers available on the Pico. And similar to its UART channels, you can access them ...

For testing I've used the Arduino nano to emulate two devices, one I2C photoresistor sensor and one SPI PWM LED. These devices, for example, could be two different attiny85; but as the atmega368p is ...

Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will record what is going on for a set time interval, then dump the data via serial as a .csv.

The price difference between the two boards is minimal too, with the Nano available ... and TFT display module. The I2C/TWI pins on the Micro are on D2 and D3. For Arduino beginners, these two ...
