Main Project: Parking Assistant & Sensor Dashboard
Follow the complete guide, wiring table, test sequence, and supplied firmware below. The HC-SR04 measures distance; LEDs show far, approaching, and near zones; the buzzer warns at the near threshold; the LCD shows distance and servo angle; and the separately powered servo acts as a distance gauge.
What you build in this project
Main Project: Parking Assistant & Sensor Dashboard is one focused build from the Arduino UNO Sensor & Output Starter Kit - LEDs, Buzzer, Servo, Ultrasonic & LCD. It uses the parts listed below to make a working electronics example, then you can combine it with the other projects in the kit.

Parts used
UNO R3, full-size 830-point breadboard, jumper wires, resistor assortment, red/yellow/green LEDs, active buzzer module, HC-SR04, SG90 servo, 10K potentiometer, LCD1602
What to check
Wire the parts, upload the sketch from the kit page, then test this project by watching the Serial Monitor or the output behavior.
What you learn
You learn how the controller reads real sensor signals, makes a decision in code, and turns that result into a useful output.
What this project uses
Every item is in the kit — nothing extra to buy.

More from this kit
Suggested Project: LED Traffic Light
Explore digital outputs and timing by sequencing three protected LEDs. This is a suggested extension; choose and document a separate pin plan before building it.
Suggested Project: Buzzer Alert Patterns
Create simple warning patterns and learn active-high versus active-low control. Confirm the module logic before adapting the main sketch.
Suggested Project: Ultrasonic Distance Meter
Measure distance and print centimetre readings in Serial Monitor. Test with a flat target and reuse the main build's D8/D9 sensor wiring.
