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.

Arduino UNO Sensor & Output Starter Kit - LEDs, Buzzer, Servo, Ultrasonic & LCD
One of 7 projects in the Arduino UNO Sensor & Output Starter Kit - LEDs, Buzzer, Servo, Ultras… — the parts below are from that kit.

What you build in this project

Suggested Project: Ultrasonic Distance Meter 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.

Measure distance and print centimetre readings in Serial Monitor. Test with a flat target and reuse the main build's D8/D9 sensor wiring.

Parts used

UNO R3, HC-SR04, breadboard, jumper wires

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.
