Waving Hand Kit with Arduino Uno + 5 Servos
Waving Hand Kit with Arduino Uno + 5 Servos — Build a Button-Activated Robotic Hand in 1-2 Hours
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine a simple mechanism that waves hello each time you press a button. This kit guides you in wiring a tactile button to an Arduino Uno, programming it to read the input, and driving an SG90 servo to swing back and forth like a hand waving. It’s a charming first project that demystifies microcontrollers and physical motion. Whether you’re a curious child, a parent nurturing STEM skills, or a teacher running a tinkering lab, this build turns code into a visible, friendly response in just an hour or two.
What You'll Build
You’ll assemble a breadboard circuit with a pushbutton and a servo motor, then load a pre-written sketch that makes the servo arm sweep when the button is pressed. The result is a waving hand that responds instantly to touch, perfect for desk-top amusement or demonstrating input/output concepts. The entire project stays on the breadboard, so there’s no soldering required, and all connections are clearly documented.
What You'll Learn
- How to read a digital button press and debounce it in code
- Controlling an SG90 servo’s angular position using Arduino’s Servo library
- Wiring a pull-down resistor to stabilise input signals
- Translating real-world interactions into programmed motor responses

Who This Kit Is For
Perfect for young makers (age 5+) exploring robotics for the first time, this kit aligns with CBSE Class 6-10 science curriculum and ATL Tinkering Lab activities. B.Tech ECE first-year students can use it as a foundational microcontroller project. Even parents looking for hands-on STEM gifts will find it an ideal introduction to Arduino and servo control.
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 or message our WhatsApp support to access the AI companion. It provides step-by-step audio and visual instructions, and our team can help troubleshoot in real time.
Can a 5-year-old assemble this kit independently?
Adult supervision is recommended for younger builders, but the colour-coded wires and large breadboard make it easy to follow the visual guide. The AI companion uses simple language and pictures to walk them through each connection.
What if the servo doesn’t move when I press the button?
Double-check the pull-down resistor connection on the button and ensure the servo’s signal wire is on pin 9. Our AI companion includes a diagnostic mode that will highlight wiring mistakes specific to this circuit.
Can I modify the code to make the hand wave continuously without pressing the button?
Yes, you can edit the Arduino sketch to loop the sweep motion automatically. The AI companion even includes a variant code snippet that does exactly that, teaching you about loop structures and delays.
Single SG90 servo sweeps back and forth to wave like a hand when button pressed.
