I2C or I2<\/sup>C is short for Inter-Integrated Circuit, a synchronous serial communication protocol developed by Phillips for communication between a fast Microcontroller and relatively slow peripherals (like Memory or Sensors) using just two wires. Hence, it is sometimes also known as TWI (Two Wire Interface).   It can support 112 devices and run over 1 meter in length with proper setup. <\/p>\n
You have a SDA (Data pin) and SCL (Clock Pin).   It allows many devices to only use 4 wires to connect.   You have VCC, Ground, Clock and Data pins.<\/p>\n
The breadboard in front of the Arduino devices has two +\/- power rails.  The one closest to the Arduino device uses blue and yellow wiring.  Blue = SCL (Clock)
Yellow = SDA (Data)<\/p>\n
The top +\/- power rail connects the 5V and Ground
Red = 5V VCC
Green: Ground<\/p>\n
The Raspberry Pi T-Cobbler has 5V on left side and 3.3V on right side power rails.   The Sparkfun Bi-Directional Logic Level Converter allows 3.3V on left side for the Raspberry Pi and 5V on right side for Arduino devices.   It has the I2C Bus connecting through the component.    Raspberry Pi is the Master and Arduino devices are all slaves.   The Raspberry Pi is a Micro-computer that is more powerful than the Arduino devices and easier to program.   <\/p>\n
Raspberry Pi OS with Kernel 6.6.5 from December 2023 is installed on the Raspberry Pi.  It is 64 bit.   I connected the I2C LCD screens to it in this picture.   <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

This could go in both Arduino and Raspberry Pi sections.\u00a0\u00a0 I have a SparkFun Logic Level Converter – Bi-Directional\u00a0 (LLC-BD) module.\u00a0 The red device in the middle.\u00a0\u00a0 On one side is LV (Low Voltage) and the other side is HV (High Voltage).\u00a0\u00a0\u00a0 Low Voltage is the 3.3V Raspberry Pi and the High Voltage is the 5V Arduino UNO.\u00a0\u00a0 Grounds are connected across along with each pins 1,2,3,4.\u00a0\u00a0 So LV1 goes to HV1.\u00a0\u00a0\u00a0 This device is I2C capable.\u00a0\u00a0 The Arduino has both 3.3V and 5V connected to the LLC-BD.\u00a0\u00a0<\/p>
Raspberry Pi 5V<\/p>
The 5v pins give direct access to the 5v supply coming from your mains adapter, less power than used by the Raspberry Pi itself. A Pi can be powered directly from these pins, and it can also power other 5v devices. When using these pins directly, be careful and check your voltages before making a connection because they bypass any safety features, such as the voltage regulator and fuse which are there to protect your Pi. Bypass these with a higher voltage and you could render your Pi inoperable.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t
