Missed a dose because time slipped by? 💊⏰ This Automatic 3D Medicine Dispenser remembers for you and guides you with light, sound, and a clear LCD. It turns daily dosing into a calm, repeatable routine.
Unlike a pillbox that only stores tablets, this system manages the experience. You see your schedule on screen, get a friendly prompt when it’s time, and watch the tray move so you know action happened.
The interface stays friendly for all ages. A simple keypad, obvious confirmations, and one-press controls reduce stress and mistakes. The result is confidence—every single time.
Why Build It Automatic 3D Medicine Dispenser?
First, it solves a real problem: timing doses while you work, study, or care for family. The dispenser handles the timing and the reminders, so you can focus on life rather than watching the clock.
Second, it showcases assistive tech done right. Clear text, colored LEDs, and audible cues work together with gentle motion, creating feedback you can see and hear. That combination is reassuring for seniors and beginners alike.
Third, it’s adaptable. The same platform can support vitamins, pet meds, feeding intervals, or lab timing tasks. Because the enclosure is 3D-printed, you can tailor size, labels, and compartments to your needs.
What You’ll Learn
By building this Medicine Dispenser, you’ll:
- Design trustworthy time-based interactions: set a duration, verify it on-screen, and get unmistakable feedback when it’s time to act — the set → confirm → act loop behind dependable products.
- Build stateful flows: handle pause / resume / cancel gracefully, manage multi-step cycles, honor user intent, and always return to a safe home position.
- Use multi-sensory cues + motion: green blink + tone for each dispense, red + alarm when the session ends, and smooth, visible servo rotation users can understand at a glance.
What You’ll Need:
- 4X4 Button Pad Sealed Membrane
- Servo Motor MG996R
- LCD I2C Blue
- 8 x AA Battery Holder
- LED 5MM RGB Clear
- Arduino Uno
- USB Cable Type B
- Alkaline Battery AA
- Jumper Wires
- Third Hand with Magnifying Glass
- Metal Soldering Iron Stand with Sponge
- Soldering Iron
- Soldering Lead
- Multifunctional Wire Stripper Cutter
To make the wiring of your Medicine Dispenser neat and easy to connect, it’s important to use the right tools. Jumper wires help you quickly link components without messy soldering on a breadboard. A Third Hand with Magnifying Glass holds your wires steady while you solder, giving you better precision and safety. The Metal Soldering Iron Stand with Sponge keeps your Soldering Iron safely in place and clean for smooth joints. Using Soldering Lead, you can make solid, reliable electrical connections that won’t come apart easily. Finally, the Multifunctional Wire Stripper Cutter lets you trim and strip wires perfectly to the right length, avoiding tangled or frayed ends. With these tools, your project’s wiring will be organized, secure, and easy to troubleshoot or modify.
How it Works?
You choose a time unit—seconds, minutes, or hours—and enter the value on the keypad. The LCD echoes your choice for quick review. When you start, the device begins an easy-to-read countdown.
At zero, it performs a dispensing step: the green LED blinks and a tone plays, then the servo rotates the tray to the next pocket. The sequence repeats up to four times per set duration. At any moment, you can pause to hold the timer, resume to continue, or cancel to stop and return home.
After the fourth rotation, the Medicine Dispenser wraps up the session. The red LED blinks and an alarm signals completion, the servo returns to its starting position, and the screen resets. You’re immediately ready to set the next schedule.
Applications & Extensions
Home care and independence. Support seniors, busy parents, and patients with complex routines. Clear prompts reduce missed doses without requiring a phone or internet.
Clinics, classrooms, and labs. Use it as a repeatable “timer-plus-action” demo. The visible motion links “time reached” to “mechanical outcome,” which is perfect for training and science fairs.
Grow the system. Add a multi-slot carousel, rechargeable power, or a lockable lid. With Wi-Fi/Bluetooth (e.g., ESP32), send reminders, log history, or notify caregivers. You can also customize LED patterns, tones, and labels for different accessibility needs.
