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. It also includes a 4×4 keypad for setting timers in seconds, minutes, or hours. An LCD screen shows exactly what you entered. This makes it easy to double-check and fix mistakes.
In addition, it has RGB LEDs and a buzzer that give clear visual and sound alerts. This way, you always know when it’s time to take your medicine. Another important feature is its focus on user-friendly controls. If you enter the wrong value, you can clear or change it easily. You can also pause the countdown with one press. Then you can resume or cancel it at any time. This makes the dispenser very convenient for older users or anyone who needs quick and simple controls.
Another key feature is its ability to rotate four times based on the set timer. After completing those four dispensing cycles, the servo returns to its starting position. This means users can quickly set it up again for the next schedule. This cycle-based design ensures consistent medicine delivery. It also helps remind users to prepare for the next dose.
Overall, the design solves real-life problems. It makes daily medicine routines easier, safer, and more reliable. It also encourages others to create 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.
