Step-Counter-Pedometer-

A simple wearable step counter project using an accelerometer sensor and OLED display, with power switch and reset functionality. Built with Arduino for health and fitness monitoring applications.

Step Counter with OLED Display

Short Description

This project is a step counter that uses an accelerometer sensor to detect and count steps, while displaying real-time data on an OLED screen. It’s designed as a simple wearable prototype that helps monitor movement without needing a smartphone app.

Features

• Counts steps using accelerometer readings
• Displays live step count on the OLED screen
• Power ON/OFF control with switch
• Reset button to clear step count
• Low-cost, beginner-friendly wearable prototype

Components Used

Hardware

• ESP32 / Arduino board
• Accelerometer sensor (e.g., MPU6050 / ADXL345)
• OLED Display (SSD1306 or similar)
• Push button (Reset)
• Power switch
• Breadboard + jumper wires

Software

• Arduino IDE
• Wire.h & Adafruit Sensor libraries (or equivalent for your accelerometer)
• Adafruit SSD1306 / U8g2 library for OLED

How It Works

1. The accelerometer continuously measures movement in x, y, z axes (g-forces).
2. The code calculates the acceleration magnitude from these axes.
3. When the magnitude crosses a threshold value (e.g., > 1.39 g), it’s detected as a step.
4. Each valid step increases the step counter.
5. The OLED screen updates in real-time to show the step count.
6. The reset button clears the step count, and the power switch turns the device ON/OFF.
