Clap, Flash LEDs & Measure Beats Per Minute

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Clap your hands in any rhythm and watch five colorful LEDs flash in perfect sync while your Arduino calculates the exact beats per minute - a hands-on way to explore music, electronics, and code. This kit combines a sensitive KY-038 microphone with an Arduino Uno to turn rhythmic claps into a visual beat indicator, then computes BPM from the inter-clap timing. It's an engaging introduction to sensor-driven real-world applications and a delightful tool for music education at home or in the classroom.

What You'll Build

You'll assemble a standalone music visualizer that listens to your claps, measures the time between beats, and lights up a row of LEDs in sequence to match the tempo. The Arduino monitors the sound sensor for sharp peaks (claps), then uses precise timing to calculate and display BPM on the serial monitor. The LED pattern updates instantly, creating a colourful light show that helps you practice keeping a steady rhythm or invent your own clap-controlled beat patterns.

What You'll Learn

• How to interface a KY-038 sound sensor with Arduino and read analog signals to detect clap intensity
• Writing code to measure inter-beat intervals down to milliseconds using the millis() function
• Controlling multiple LEDs in sequence based on real-time rhythm calculations
• Translating the musical concept of BPM into a tangible hardware project that responds to your own body rhythm
