Morse Code Buzzer Trainer Kit with Arduino Uno
Morse Code Buzzer Trainer Kit with Arduino Uno — Decode Letters by 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.
Press a button, and hear the dots and dashes of Morse code through a buzzer while the decoded letter appears on a bright LCD screen. This kit turns learning the historic communication method into an interactive game — perfect for young explorers who want to understand how early telegraph systems worked. You’ll assemble a real-time Morse trainer that responds instantly to your touch, bridging the past and future of electronics.
What You'll Build
You’ll assemble a complete Morse code trainer that responds to your touch. Each button press triggers a short beep for a dot or a long beep for a dash, while the Arduino decodes the sequence in real time and displays the corresponding letter on the 16x2 LCD. Build it in under two hours, then enjoy practicing messages with friends or using it in school science exhibitions.
What You'll Learn
- Program Arduino to detect button presses with accurate timing for dot and dash generation.
- Control a passive buzzer to produce distinct tones for short and long signals.
- Read and write characters to an LCD via I2C communication.
- Understand Morse code encoding and real-time character decoding logic.

Who This Kit Is For
Young makers aged 8+ (with adult supervision) curious about how radios and early telecommunication worked. CBSE Class 11-12 students preparing for science exhibitions or seeking a hands-on physics project. ATL Tinkering Lab members exploring Arduino and sound, and first-year B.Tech ECE students looking for a simple but impressive mini project.
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?
Our AI companion walks you through each step with text and images; if you need human help, just WhatsApp us and a build expert will respond within a few hours.
Is coding experience required for this kit?
No, the code is provided ready to upload. The companion explains every line so you understand what it does, making it perfect for beginners.
Can this kit be used for school science exhibitions?
Absolutely. The working model demonstrates Morse code, digital input/output, and LCD display — all CBSE/ICSE curriculum topics. It’s a compact, attention-grabbing exhibit.
What letters can the kit decode?
The kit is pre-loaded to decode all 26 English letters. You can extend it to numbers and symbols using the included AI guide.
Button presses play Morse code dots and dashes on buzzer. LCD shows decoded letter.
