Summary

This circuit consists of multiple LEDs (both red and yellow) connected to a Raspberry Pi 2B. Each LED is connected in series with a 1000 Ohm resistor. The anodes of the LEDs are connected to various GPIO pins on the Raspberry Pi, while the cathodes are connected to the resistors, which are then connected to the ground (GND) pin of the Raspberry Pi.
