Summary of the Circuit

This circuit integrates a Raspberry Pi 4B with a 0.96" OLED display and an Adafruit ADS1115 16-Bit I2C ADC, along with a current sensor. The Raspberry Pi 4B serves as the central processing unit, managing data communication over I2C with both the OLED display and the ADC. The ADC is used to convert analog signals from the current sensor into digital form for processing by the Raspberry Pi. The OLED display provides a visual interface to display data or status information.

Component List

Raspberry Pi 4B

• Description: A powerful microcomputer with multiple GPIO pins for interfacing with various peripherals.
• Purpose: Acts as the central controller for the circuit, running the software and interfacing with other components.

Current Sensor

• Description: A sensor that measures the flow of current through a conductor.
• Purpose: Provides analog current measurement to be digitized by the ADC.

0.96" OLED

• Description: A small organic light-emitting diode display.
• Purpose: Displays information processed by the Raspberry Pi.

Adafruit ADS1115 16Bit I2C ADC

• Description: A high precision analog-to-digital converter that communicates over I2C.
• Purpose: Converts analog signals from the current sensor into digital data for the Raspberry Pi.
