A tiny clock that integrates air quality monitoring, a timer, and an alarm sounds cool, right? Let's get into the article and know how it is built. It is a Cyber-style multifunction clock that can monitor air quality, show real-time data, run a timer, trigger alarms, and another cool feature is that it's a mini retro game. From a technical perspective, the system is built around an ESP32-C3 microcontroller-based control unit that handles the real-time clock operations like setting an alarm, time displaying, display control and input processing.
The system checks any abnormal changes in the environment with the air quality monitoring sensor. If the sensor detects any changes like that it will send the data to the control, and the control processes the data and triggers the light as well as the buzzer to alert the user about the changes.GPIOs are configured for sensor input, user buttons, and output control, while display libraries handle dynamic screen updates and animations.
The Pomodoro timer is implemented using software timers to manage focused work and break intervals without blocking other operations, while the alarm function compares real-time clock values with user-set parameters to trigger an audio alert through a buzzer or speaker. Also as mentioned, the mini retro game, which can be played using the controls at the boredom can be more engaging, making the project an effective blend of an embedded system.
