Patient Medication Reminder Circuit

Patient Medication Reminder Circuit Using ATMEGA328/P Microcontroller is to help the doctor and patients on the schedule of how and when to take their drugs.

This project, patient medication reminder, helps in medication administration and monitoring. This system consists of an ATMEGA328P microcontroller with an inbuilt EEPROM and a real-time circuit.

This system is driven by an embedded program that inputs predefined parameters that are processed based on the input variables entered via a user interface device such as the keypad.

All the entries made on the keypad are concurrently and simultaneously displayed on the LCD panel of the device.

The logic for the processing is built into the embedded program to initiate the alert through an audio alarm. It has an alarm system and an LCD that displays the medicine to be taken at the reminder time.

Patient Medication Reminder Circuit FAQ

What is the power of the power supply?

The primary function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. The input and output are usually hardwired circuit connections, though some power supplies employ wireless energy transfer to control their loads without wired connections.

How do you remove ripples from DC?

The ripple can be reduced by smoothing capacitors which convert the ripple voltage into a smoother dc voltage. Aluminum electrolytic capacitors are widely used for this and have capacitances of 100uF or more. The repeated dc pulses charge the capacitor to the peak voltage.

Which filter is best for rectifiers?

The best type of filter for a diode rectifier consists of
A large inductor at the input end.
A large capacitor at the output end.
A small inductor at the input end.
A small inductor at the input and a large capacitor at the output.

Which device can automatically break supply?

A circuit breaker is a device used to make or break a circuit at any load, i.e., at no-load, full load, or short circuit condition. Therefore, it automatically interrupts the supply in the event of surges. An isolator is a device that operates only at no load condition after the operation of the circuit breaker.

What is an automatic power supply?

This project is designed to automatically supply continuous power to a load through one of the four sources of supply: solar, mains, thermal, and wind when any one of them is unavailable.

What does UPS stand for in computers?

Uninterruptible Power Supply: During power surges and failures, Uninterruptible Power Supply (UPS) devices keep computer systems and IT equipment safe and operational. An Uninterruptible Power Supply (UPS) provides battery backup power when the flow of electricity drops to an inadequate voltage or stops.

What is better, UPS or AVR?

An AVR provides 24/7 protection to your appliances. It does so by regulating the voltage fluctuations in the power supply. This ensures the output voltage delivered to the appliance remains constant at all times. A UPS provides an uninterruptible power supply during power outages.
