Circuit Documentation
Summary
The circuit in question appears to be a microcontroller-driven LED array, utilizing an Arduino Mega 2560 to control multiple LEDs through digital output pins. The LEDs are arranged in pairs of red and green, each pair being connected to a resistor to limit the current. The cathodes of the LEDs are connected to the ground (GND) of the Arduino, while the anodes are connected to digital pins through the resistors. The resistors are of two values, 100 Ohms and 220 Ohms, to set appropriate current limits for the LEDs.
