Fitness Step Counter Pro Kit with Arduino Uno + MPU6050
Build a Step Counter & Prove F=ma with Arduino Uno + MPU6050
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a wearable fitness step counter that counts every stride with precision, then flip it into a physics lab to prove Newton’s second law — all on a single breadboard. This kit bridges real‑world fitness tracking and core physics concepts, making it perfect for school projects, science fairs, and curious young minds. You’ll connect an MPU6050 accelerometer, a load cell, and an LCD screen while writing code that turns raw sensor data into meaningful measurements.
What You'll Build
A fully functional step counter that uses the MPU6050’s 3‑axis accelerometer to detect walking motions and displays the real‑time step count on a 16x2 LCD. Simultaneously, you’ll assemble a force‑measurement subsystem with a 1 kg load cell and HX711 amplifier. By gently pushing the load cell while the accelerometer logs acceleration, you’ll collect data to verify F = ma — a hands‑on physics experiment with immediate visual feedback.
What You'll Learn
- How to interface a 3‑axis accelerometer (MPU6050) with Arduino and read acceleration values
- Calibrating a load cell and HX711 amplifier for accurate force measurement
- Displaying real‑time sensor data on an I2C‑controlled 16x2 LCD
- Processing acceleration peaks to count steps and using serial plotter to validate F = ma

Who This Kit Is For
Students in CBSE classes 5–12 performing physics practicals or smart school projects, B.Tech ECE/EEE freshmen tackling sensor integration assignments, and participants in ATL Tinkering Labs or science exhibitions. If your child loves wearables and has a knack for coding, this kit gives them a solid headstart in embedded systems and Newtonian mechanics — all without a soldering iron.
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 for instant access to the AI companion, which has been trained on this specific kit. You can also reach us on WhatsApp for human backup — typical response within 1 hour during IST business hours.
Can this kit count steps accurately for a full workout?
Yes, the MPU6050 detects acceleration patterns that match walking and running. With the provided code, you’ll achieve ~90% accuracy; advanced users can fine‑tune filters for even better results.
Does the load cell really show F=ma? How do I set it up?
Absolutely. The load cell measures the force applied to it, while the MPU6050 logs simultaneous acceleration. By comparing these values in the serial plotter, you’ll see a linear relationship — a classic physics lab right on your breadboard.
Do I need soldering or prior coding experience?
No soldering is required — everything plugs into the breadboard. We provide the complete Arduino sketch; you only need to upload it via the IDE. The code is well‑commented for those who want to explore further.
Fitness — Load cell measures force. MPU6050 measures acceleration. Verify F = ma experimentally.
