Summary of the Circuit
This circuit appears to be a simple microcontroller-based system that uses an Arduino UNO to control an LED through a digital output pin (D13). The LED's brightness can potentially be adjusted using a trimmer potentiometer. The resistor is likely used to limit the current through the LED to prevent damage. The potentiometer's wiper is connected to an analog input (A5) on the Arduino, which could be used to read the voltage level and adjust the LED brightness accordingly.
Component List
