Prototype-Medication-Alarm-Clock

A prototype medication alarm was built using the STM32 microcontroller.

DISCLAIMER: This is not intended for medical use in any form; it is meant for educational purposes only.

Features:

• Easy-to-use text-based UI
• Set the time
• Create multiple alarms
• When the alarm goes off, a buzzer plays, and the LCD screen blinks
• The buzzer has Low/high volume settings
• LCD blinking can be toggled on and off

Requirments

• STM32F401RE
• I2C 1602 LCD Display Module 16X2
• I2C 1602 LCD Display Module 16X2 Library can be found here. Note: "liquidcrystal_i2c.c" goes in the "Src" folder, and "liquidcrystal_i2c.h" goes in the "Inc" folder
• Breadboard
• 6x6x4.3mm TACT Switch Push Button for Arduino (2 of these)
• basic Arduino resistors for the buttons
• Dupont Jump Wires
• STM32CubeIDE
• Universal Passive Buzzers (2 of these)

Circuit Layout:

The left button is to scroll down. The Right right button is to scroll up. The blue built-in button on the STM32 is to select.
