Draw a passive stereo-to-mono audio mixer using only resistors, nonpolar capacitors, ground symbols, and labeled connection points. Do not draw connector symbols. LEFT connects through C1, 2.2 microfarads, then R1, 10 kilohms, to MONO. RIGHT connects through C2, 2.2 microfarads, then R2, 10 kilohms, to the same MONO node. R3, 100 kilohms, connects MONO to GND. OUT connects directly to MONO. Place LEFT and RIGHT on the left in separate horizontal rows. Place OUT on the right. Show a junction dot where the two branches and R3 meet. Label that junction MONO. Preserve all stated component values exactly.

Keep the existing Audio Mixer circuit and component values. Replace J1 LEFT, J2 RIGHT, and J3 OUT with two-pin connectors only. Pin 1 is signal and pin 2 is ground. J1 pin 1 connects through C1 and R1 to MONO. J2 pin 1 connects through C2 and R2 to MONO. J3 pin 1 connects directly to MONO. R3 connects MONO to ground. Pin 2 of all three connectors connects to ground. Label the junction of R1, R2, R3 and J3 pin 1 as MONO. Arrange the branches to avoid wire crossings. Show junction dots wherever wires connect. Use nonpolar capacitor symbols for C1 and C2.

An audio mixer with two input connectors labeled LEFT and RIGHT. Each input connects through a 2.2 microfarad capacitor and then a 10 kilohm resistor to a shared node labeled MONO. A 100 kilohm resistor connects MONO to ground. An output connector connects to MONO. Use standard schematic symbols.

Generate a clean, top-down, 3D-rendered breadboard diagram in the style of Fritzing. White background. Components: 1 large breadboard (bottom) and 1 small breadboard (top). 1 battery pack (3 AA batteries) on the far left. 1 red 4-pin DIP switch on the bottom-left. 4 black IC chips (14-pin) stacked vertically in the middle of the large breadboard. 4 LEDs (Red, Green, Yellow, Blue) in a vertical row on the far right. Tan resistors (220 ohm) next to the LEDs. Tan resistors (10k ohm) next to the DIP switch. Wiring Instructions (Strictly follow these): Power: Red wires connect the battery (+) to the top and bottom Red rails. Black wires connect the battery (-) to the top and bottom Blue rails. Short red wires go from the Red rail to Pin 14 of all 4 chips. Short black wires go from the Blue rail to Pin 7 of all 4 chips. Inputs (Green Wires): Wires run from the DIP switch horizontally to the left-side input pins of all 4 chips. 10k resistors connect from the switch inputs to the Blue (-) rail. Outputs (Colored Wires): Orange, purple, white, and grey wires run from the output pins on the right side of the chips directly to the long legs of the 4 LEDs. LED Grounds: 220-ohm resistors connect the short legs of the LEDs to the bottom Blue (-) rail. Critical Rules: Do NOT route wires under the chips. Do NOT connect red wires to blue rails. The wiring must look physically possible, neat, and flat against the breadboard.
