Summary of the Circuit
This circuit consists of an Arduino Nano microcontroller, a 9V battery, a photodiode, a resistor, and a yellow LED. The Arduino Nano is the central processing unit of the circuit, interfacing with the photodiode to detect light levels and controlling the LED based on the input from the photodiode. The 9V battery provides power to the circuit, while the resistor is used to limit current to the photodiode. The LED serves as an output indicator.
