This Stepper Motor Control PCB design will integrate multiple sensors and modules to create a Health Monitoring & Control System. The system will authenticate users via RFID, measure Heart Rate (HR) and Blood Oxygen Level (SPO2), display system status on an LCD, take inputs via a Keypad, control a Stepper Motor with A4988 Stepper Motor Driver, and trigger an Alarm (Buzzer) if HR or SPO2 levels exceed set thresholds.
The PCB will include headers and connectors for interfacing with external modules while maintaining a compact and efficient design.

Components used in Stepper Motor PCB Design Project:
Pulse Oximeter (MAX30100) – Measures heart rate and SPO2 levels.
RFID Module (MFRC522) – Used for user authentication.
16×4 I2C LCD Display – Displays system messages and real-time data.
4×4 Keypad – Allows user interaction.
Stepper Motor – Controlled for specific actions.
A4988 Stepper Motor Driver– for controlling stepper motor.
Buzzer – Alerts the user when HR/SPO2 crosses thresholds.
SoftwareSerial – Enables serial communication with another device.
