Circuit Documentation

Summary

This circuit consists of multiple BC547 transistors, resistors, and LEDs of different colors (red, blue, and green). The circuit is powered by a 5V connector and includes ground connections. The transistors are used to control the LEDs, with resistors limiting the current to the LEDs. The circuit does not include any microcontroller code.
