Example 2: Medicine Reminder and Vending Machine

image

Function: A medicine vending machine to store and give doses via medicine bottles and alert patients at prescribed times.

Electrical components involved:

  1. Arduino Mega 2560 (Alternatively, Arduino Nano or Uno can be used.) × 1
  2. Rotary Encoder with Push-Button (This will be used to provide Dose Time input to the microcontroller.) x1
  3. SG90 Micro-servo motor (Servo motors will be used to implement rack mechanism to drop medicine boxes. And clear the medicine rack if a patient misses a dose, so as to avoid confusion when next dose drops) x5
  4. DS3231 RTC Module(To keep track of time) x1
  5. MP3 player module and speaker(This will play audio tones stored in SD card. Alternatively, a buzzer can be used to keep cost low.) x1
  6. Adafruit RGB Backlight LCD - 16x2(To display upcoming medicine dose time.) x1
  7. LED (generic) x1
  8. IR sensor (To detect when a dose drops and is taken by patient to update information in SD card.) x1
  9.  Micro SD card module and SD card

(Used to store dost history of the patient) x1 (Tape, cutter…) Sub-systems involved:

  1. Assembling of articles

  2. Medicine vending rack mechanism using Two Servos

  3. Medicine Dose Boxes-

  4. SD Card data logging-
