Sep 16, 2019 — In the third installment of our I2C tutorial, I will show you two methods of connecting a 3.3-volt Raspberry Pi to a 5-volt Arduino Uno. Code .... I2C bus supports multiple slave devices and multiple master devices. Many Sensors use this serial communication protocol to transfer their data to microcontrollers .... esp32. The esp32 chip offers two I2C controllers, that can act both as master and slave and communicate in standard and fast speed. The I2C ... 939c2ea5af
