The “Medicine Vending Machine” is an innovative automated system designed to dispense medicines based on age groups using an Arduino Uno microcontroller, 4-channel relay board, DC motors, push buttons, and an LCD display. The system features four push buttons, each corresponding to a specific age group (e.g., child, adult, senior). Upon selecting a particular age group, the user presses the corresponding push button, which triggers a series of events. The Arduino Uno processes the selection and activates a DC motor through the relay board to unlock the appropriate medicine compartment. The LCD display provides real-time feedback to the user, displaying the chosen age group and instructions. The DC motors are responsible for mechanically dispensing the selected medicine from the designated compartment. This system aims to offer a simplified, self-service method for dispensing medicine, ensuring accurate dosage based on the selected age group, enhancing convenience, and minimizing human error in a pharmacy or healthcare setting.

Objectives:

1. Design an automated system for dispensing medicine based on age group.
2. Use push buttons to select the appropriate age group.
3. Control DC motors to release the selected medicine.
4. Provide real-time feedback using an LCD display.
5. Minimize human intervention and errors in medicine dispensing.
6. Implement the system using Arduino Uno and a 4-channel relay board.

The major building blocks of this project are:

• Regulated power supply.
• ARDUINO UNO Microcontroller.
• 4 Channel Relay.
• 4 DC motors.
• 4 Push buttons.
• LCD display.

Software’s used:
