Earthquake Vibration Logger Kit with Arduino Mega + NRF24
Earthquake Vibration Logger Kit — Master-Slave Robotic Arm with Haptic Feedback
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This advanced kit recreates the core principle of remote tremor monitoring — a master arm with potentiometers mirrors a slave arm wirelessly, while vibration motors feed resistance back to the operator. It’s a hands-on introduction to seismology instrumentation, teleoperation, and haptic control loops. Every sensor, actuator, and wireless module is included, pre-tested to form a working system right out of the box.
What You'll Build
You’ll assemble two articulated arms, each with three degrees of freedom, linked by NRf24L01 2.4 GHz transceivers. The master arm’s six potentiometers send real-time joint positions to the slave arm, whose MG90S servos replicate the motion precisely. When the slave encounters an obstacle – or ground vibration – coin vibration motors on the master provide immediate tactile feedback, creating a closed-loop force-reflective system suitable for earthquake simulation or remote device control.
What You'll Learn
- Setting up dual Arduino Mega 2560 communication via NRF24L01 and managing reliable packet loss scenarios
- Controlling multiple servos with PCA9685 I2C driver to achieve smooth, synchronized motion
- Implementing force reflection algorithms that convert slave-side resistance into master-side vibration intensity
- Calibrating potentiometer analog inputs and mapping them to servo angles for accurate teleoperation

Who This Kit Is For
Designed for B.Tech ECE/EEE students tackling Smart India Hackathon teleoperation challenges, final-year projects at IIT/NIT/VIT/BITS, or researchers setting up a low-cost vibration logging testbed. The master-slave architecture reflects real seismic sensing deployments, making it a practical tool for instrumentation lab coursework or DIY seismology enthusiasts.
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 chat with our AI companion trained on this exact project — it covers wiring, calibration, and debugging. You can also message us on WhatsApp for direct engineer support.
Can I modify this for a college seismology project?
Absolutely. The haptic feedback loop and wireless communication are documented in the build guide, allowing you to adapt trigger thresholds, sensor inputs, or data logging for earthquake simulation experiments.
Is soldering experience required?
Yes, this is an advanced kit. You’ll solder NRF24 modules, capacitor arrays, and PCB connections. We include a soldering iron and solder wire, but assume prior experience with through-hole soldering.
How far does the wireless link work?
The NRF24L01 with integrated PCB antennas provides a stable 2.4 GHz link up to 100 meters in open space. The 100nF capacitors filter power-supply noise, ensuring reliable data transfer even during motor load fluctuations.
