I2C data transfer in a readable text format between Pico as Master and Arduino as Slave and Two Picos one as Master and other as Slave. I2C protocol in principal can have two masters on the same bus, ...

The Arduino Nano and Raspberry Pi Pico support different input voltages, so they also use different power sources. However, they can both be powered with a 5V supply via their onboard USB ports.

The organization has introduced the Raspberry Pi Pico, a $4 board meant to offer a gentle entry point for microcontrollers. Think of it more as a complement to a Pi aimed at tasks like analog input.

I2C protocol in principal can have two masters on the same bus, but this is not a practical or a good practice as the master creates the clock on the databus (SCL) which the data (SDA) is transferred ...
