Servo Gripper Open Close Kit with Arduino Uno + Servo
Servo Gripper Open Close Kit: Build a Button-Controlled Gripper with Arduino Uno
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 watch the gripper snap open; press again and it closes. This kit transforms a humble SG90 servo into an interactive machine, teaching the fundamentals of motor control, Arduino programming, and circuit building in one tidy project. Designed as the perfect first step into robotics, it gives young makers and students the confidence to see electronics in motion.
What You'll Build
A responsive gripper unit that toggles between fully open and closed positions with each button press. Two LEDs indicate the gripper’s state—red for closed, green for open—giving instant visual feedback. The entire circuit is assembled on a breadboard, making every wire and connection visible and easy to understand.
What You'll Learn
- How a servo motor works and how to control its angle using PWM signals from an Arduino Uno
- Writing Arduino code that reads digital input from a tactile button and responds with precise servo movements
- Assembling a reliable circuit on a breadboard, including resistor placement for stable button readings
- Using LEDs as status indicators to make your project interactive and user-friendly

Who This Kit Is For
Ideal for ATL Tinkering Lab students tackling their first robotics project, CBSE Class 8‑12 learners exploring electronics, and B.Tech ECE first-semester students who want hands-on servo experience. Also suits young makers and parent‑child build sessions for ages 8+.
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 your AI build companion, which walks you through every step. For additional help, reach us on WhatsApp for one-on-one guidance.
Do I need any prior coding experience?
No. The kit includes commented code that explains each line. The AI companion guides you through uploading it to the Arduino, making it easy even if you’ve never programmed before.
What can this gripper actually grip?
The basic build moves the servo horn between two positions; you can attach a simple jaw piece (cardboard or plastic) to grip lightweight objects like craft sticks or a small pen cap. It’s a starting point for robotic claws and automated pick-and-place systems.
Is the kit safe for children aged 5 and up?
Yes. All components operate at low voltage (9V battery) and there’s no soldering. Adult supervision is recommended for children under 8 during assembly to ensure correct connections and battery handling.
Single SG90 servo drives a simple gripper. Button toggles between fully open and closed positions.
