How It Works

The DoseRight Smart Automatic Medicine Manager is an IoT-enabled medical adherence system coordinated by an ESP32-S3-BOX-3 microcontroller. When a scheduled dose time arrives—managed via a full-stack software architecture involving React, Vite, Node.js, and a MongoDB database—the system triggers the physical dispensing mechanism. The central actuation uses a 28BYJ-48 stepper motor paired with a ULN2003 stepper motor driver to precisely rotate internal compartment plates, aligning the correct medication container with the dispensing chute. Concurrently, an SG90 servo motor acts as a secondary gate or locking mechanism to release the pills smoothly. Once the medication drops through the chute, an IR sensor module detects the physical passage of the pills to verify that the patient has indeed retrieved their dose. If manual input is required, users can interact directly with push buttons on the device. Power is supplied cleanly via a 5V power adapter (~2A) connected through a Type-C connector, governed by an onboard power switch to safely turn the unit on and off. The ESP32 handles local automation while continuously communicating with the cloud backend to log adherence data, update schedules, and track remaining pill inventories.

Safety Precautions

Ensure a stable 5V power supply (~2A) to prevent motor jitter or unexpected resets. Do not power motors directly from the ESP32 GPIO pins; always use appropriate drivers like the ULN2003 for the stepper motor and maintain a common ground reference across all circuits.

Frequently Asked Questions

Why is a separate 5V (~2A) power adapter required instead of powering everything through the computer USB port?

Motors like the 28BYJ-48 stepper and SG90 servo draw significant current spikes during operation. Drawing this power directly through a standard computer USB port or the ESP32 regulated pins can cause voltage drops, leading to motor jitter, erratic behavior, or unexpected microcontroller resets.

Can I program the ESP32-S3 using the standard Arduino IDE?

Yes, the ESP32 platform is fully compatible with the Arduino IDE (via the ESP32 board package) as well as the native ESP-IDF framework, allowing you to choose the development environment you are most comfortable with.

What is the purpose of the ULN2003 driver module?

The ESP32 GPIO pins operate at 3.3V and cannot supply enough current to drive the coils of the 28BYJ-48 stepper motor directly. The ULN2003 driver acts as an intermediary, using the low-current signals from the ESP32 to safely switch the higher current and voltage needed by the motor coils.
