Notes:
The Power Supply feeds both the Arduino (via VIN) and the LM7805 Regulator.
The LM7805 creates a steady 5V Rail for powering most sensors, actuators, and modules.
The Arduino provides an additional 3.3V Rail for the BMP280, ESP8266, and SIM 800L.
Signal connections between devices are represented by arrows. Connections such as digital/analog signals, I2C, and TX/RX lines are simplified for clarity.
Supplemental components like capacitors, diodes, and MOSFETs for switching and protection are shown.
Let me know if you need any further adjustments or additional details.
