Robo Cy

New build: Mini Piano.

🎹 What if your code could play music?

This started as a few buttons…
and turned into a fully working mini piano using a compact DIY setup.

🧠 ESP32 – the brain.

🌫 Push Buttons – input.

🔔 Speaker – sound.

💡 RGB LED – light show.

🔌 Perfboard & resistors – the structure.

Press a key → hear a note
Add LEDs → now it feels alive
Add code → now it plays songs on its own

From wiring resistors…
to mapping notes…
to actually playing melodies...

This is where hardware meets creativity.

And yeah…
We’ve been playing with it non-stop 😅

🔧 New Build: Guess the Distance

A fun DIY project that measures how far an object is and displays the distance in real time. Perfect for learning about sensors, microcontrollers and interactive electronics. 📏🤖

🧠 Kypruino UNO+ v0.8.1 – the brain.
Controls the system, reads the sensor data and updates the display.

📡 Ultrasonic Sensor – the detector.
Measures the distance to nearby objects using ultrasonic waves.

🖥 Oled 0.91" Display – the interface.
Shows the measured distance clearly in real time.

🔌 Ultra-Compact 5V Module – the power.
Provides stable power for the whole system.

🧩 Breadboard 170 Tie Points – the build platform.
A compact way to connect all components and prototype the circuit.

Small setup.
Smart sensing.
Interactive learning.

Can you guess the distance? 📏
