At Arduino Expert we designed and developed a fully customized IoT Pill Dispenser using Arduino UNO R4 Wi-Fi for a healthcare client who required a reliable, remotely manageable, and intelligent medication management system. This project reflects our deep expertise in Product Design and Development, Embedded Systems Development, and IoT App Development, where hardware precision meets smart cloud connectivity.

The primary objective of this Arduino Project was to automate medication dispensing while allowing caregivers and users to monitor and control schedules remotely through a mobile IoT platform. The system integrates mechanical dispensing, sensor-based confirmation, environmental monitoring, audio alerts, and real-time cloud synchronization — all powered by a robust embedded architecture.

Unlike traditional pill reminder systems that only generate alarms, this solution physically dispenses medication at the correct time, verifies successful dispensing using sensors, and logs the event to the cloud for real-time tracking. The device also monitors ambient conditions and patient temperature, making it a comprehensive smart healthcare solution.

Project Overview IoT Smart Pill Dispenser

The client required a smart medication management system capable of:

• Automated pill dispensing at scheduled times
• Remote configuration via IoT app
• Audio and buzzer reminders
• Environmental monitoring
• Body temperature measurement
