Automatic 3D Medicine Dispenser

The Automatic 3D Medicine Dispenser is a great example of how an Arduino project can combine different components for real-world use. It uses a servo motor to dispense medicine and includes a 4×4 keypad for setting timers in seconds, minutes, or hours. An LCD screen clearly shows what you’ve entered, making it easy to double-check and fix mistakes. It also includes RGB LEDs and a buzzer that provide clear visual and sound alerts. So you always know exactly when it’s time to take your medicine.

Another important lesson from this project is the focus on user-friendly controls. If you enter the wrong value, you can easily clear or change it. You can pause the countdown with one press, then resume or cancel it at any time. This makes the dispenser especially convenient for older users or anyone. Who might need to quickly stop or adjust the machine dispenser. It demonstrates how important it is to design systems that prioritize the user experience, even with simple electronics.

One more key feature is its ability to rotate four times according to the set timer. After completing those four dispensing cycles, the servo automatically returns to its starting position. So users can set it up again for the next schedule. This cycle-based design ensures consistent medicine delivery while reminding the user to prepare for the next round. It solves real-life problems by making daily medicine routines easier, safer, and more reliable. It encourages others to design their own assistive or healthcare devices using basic electronics.

To make the wiring of your project 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.
