Sound Speed Measurement Kit Kit with Arduino Uno
Sound Speed Measurement Kit with Arduino Uno: Hands-On Physics Experiment to Measure Speed of Sound
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Experience the physics of sound waves come alive as you build a working speed-of-sound measurement device. Clap your hands and watch the LCD display the calculated speed—just like a real scientific experiment. Designed for young learners, this kit turns abstract classroom concepts into a tangible, shareable project.
What You'll Build
You'll assemble a breadboard circuit with two microphone amplifiers, an Arduino Uno, and an LCD screen. Send a sound burst—a clap or a snap—and the system instantly calculates the speed of sound using the time difference between mic signals. It’s a hands-on way to explore wave physics, ideal for school exhibitions and science fairs.
What You'll Learn
- How to wire and calibrate two microphone sensors for time-of-arrival detection
- Programming an Arduino to measure microsecond-precision time intervals
- Understanding the physics of sound propagation and the time-of-flight principle
- Displaying real-time measurements on an LCD using I2C communication

Who This Kit Is For
This kit is perfect for CBSE Class 9-12 students looking to demonstrate sound speed in their physics practicals, ATL lab coordinators running STEM workshops, and curious young minds aged 10+ who enjoy building electronics. Even parents guiding early STEM exploration will find it an engaging project that reinforces textbook learning with a real working device.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access the AI companion trained for this kit; it guides you step by step. You can also reach us via WhatsApp for personal assistance.
Does this kit require soldering?
No soldering is needed. All connections are made on the included 400-point breadboard using the pre-cut jumper wires.
Can I use this kit for my school science exhibition?
Absolutely. The LCD screen shows real-time speed calculations, making it an impressive exhibit for physics demonstrations and science fairs.
How accurate is the speed measurement?
With proper microphone spacing and a clean sound source, the kit achieves accuracy within 2-3% of the expected 343 m/s, ideal for educational projects.
Two mics at known distance measure sound arrival time to calculate speed of sound.
