Circuit Documentation

Summary

This circuit integrates various components including touch sensors, LEDs, resistors, a solar panel, a Li-Ion battery, a charging module, an Arduino UNO microcontroller, a common cathode RGB LED, an OLED display, and a voltage sensor. The circuit is designed to interact with touch inputs, display information on an OLED screen, and control LED states. It is powered by a solar panel that charges a Li-Ion battery, which in turn powers the circuit. The Arduino UNO serves as the central processing unit, interfacing with the touch sensors, OLED display, and voltage sensor to perform the desired functions.

Additional Notes

• The provided code is a template and does not contain any functional code specific to the circuit's operation.
• Further implementation is required to handle input from the touch sensors, control the LEDs, read from the voltage sensor, and display data on the OLED screen.
• The code should be expanded to include pin mode declarations, touch sensor reading, LED state control, voltage sensing, and OLED display updates.
