This timer is designed as an aid to studying, named after the pomodoro method where you study for a certain amount of time then take a break. The timer can be set to any minute amount between 0 and 99 minutes, allowing the user to set a specific time, then the user can put their phone in the timer and will blare an alarm if the phone is removed before the time is up. The system is controlled using an ESP32-WROOM-32 microcontroller. The sensor used is the HD-DS25CM Infrared break beam sensor, which can detect when the phone is in the timer, due to the IR beam being sent by the transmitter side being broken. The timer displays the time using an EONE 1602A-1 LCD display, with a PWM signal sent from the microcontroller to control the brightness, which can be toggled between 3 brightness levels using the buttons on the top of the timer. The most notable accomplishment of this project was getting the entire system working. Potential areas of improvement include a changeable volume for the alarm and better space management inside the timer.
