Circuit Documentation
Summary of the Circuit
This circuit appears to be a simple LED array controlled by a Raspberry Pi 4B. There are three LEDs of different colors (red, green, and yellow), each with a corresponding resistor. The anodes of the LEDs are connected to the 3V3 power supply from the Raspberry Pi, while the cathodes are connected to ground (GND) through their respective resistors. This configuration suggests that the LEDs are intended to be driven by the Raspberry Pi's GPIO pins, although the specific control mechanism is not provided in the code input.
Component List
LED: Two Pin (red)
- Description: A red LED with two pins: anode and cathode.

Documented Code
No code was provided for the microcontroller in the circuit. To control the LEDs, code would need to be written and deployed to the Raspberry Pi 4B. This code would typically initialize the GPIO pins as outputs and then toggle them to turn the LEDs on and off. Since no code is available, this section cannot be completed at this time.
