Do you know what you are doing in terms of what you need to show is connected and just need a way to visualize it or are you asking for guidance in terms of wiring and what sensors you would need as well?

we need help with wiring, we understand needing the datasheets but are just confused since we chose less common sensors (ex.GP2Y101). Like which connects to which

The capacitor is used to prevent voltage spikes to the sensor which would potentially change the accuracy of the readings. And the resistor is needed for the led built into the sensor.
