Distance Detector
Project 3 out of 18
Create a device that measures distance with sound waves by building your very own Distance Detector.
Order NowPut the skills you’ve learned to the test by creating a Distance Detector. The Distance Detector will show the results of how far away something is using LEDs and sounds. Instead of getting a full map of the components and wiring like the past two project kits, you get to be the circuit creator! You’ll get the basic layout of the electronic components and determine the wiring of the circuit based on the code. Not to worry, you learned a lot in the first two project kits, so you’re ready. Determine how far away an object can be before it’s detected, reverse the order that the LEDs illuminate, and add more LEDs to the end of the sequence.
What you'll receive in the Distance Detector project kit:
Red LEDs (2)
White LEDs (2)
Yellow LEDs (2)
Green LEDs (2)
1/4W, 220 Ohm Resistor (7, 2 extras)
M-M Jumper Wires (13+)
Piezo Buzzer
Breadboard
Ultrasonic Sensor
USB Data Cable
UNO R3 (Arduino Compatible
You’ll learn all about ultrasonic sensors and how they work in the Distance Detector project kit.
Electronic Components. Unlock devices that you’ve likely encountered in automatic doors, or in backup technology in cars.
Circuitry. Create your own circuit using what you’ve learned so far.
Programming You’ll learn about detecting variable input values and troubleshooting with the serial monitor.

Lesson Preview
After you’ve figured out the wiring of your Distance Detector project kit and made it fully operational, you’ll be challenged even further:
- Use the serial monitor to determine the maximum distance the object can detect.
- Set the buzzer to only sound when the red LEDs light up.
- Reverse the order that the LEDs light up.
- Add the green LEDs to the breadboard and your code to illuminate when an object is at its closest detectable distance.
