Abstract

In today's world, procrastination and difficulty getting out of bed are common challenges for many people. This project tackles these problems by developing an alarm system based on a weight sensor using Arduino Uno. The system aims to improve morning motivation and reduce laziness by ensuring that users have to physically get out of bed to deactivate the alarm. The design incorporates a weight sensor and an Arduino Uno microcontroller, a keyboard for entering weight parameters, and the other components we'll look at below. To deactivate the alarm, the user has to stand up and place their foot on the sensor, which detects their weight. The alarm only stops if the weight detected is within ±2.5% of the pre-set value, which ensures that the user has actually got out of bed and not used an object to fool the system. The prototype features a buzzer to trigger the alarm, an LCD screen to display relevant information and an RTC timer for precise alarm management, all housed on a printed circuit board for durability. By applying this physical requirement and focusing on accurate weight detection, the project aims to provide an effective solution to morning procrastination, helping users to start their day more actively.
