SmartClock

A small "smart" alarm clock for IoT course.

Idea

A small clock with alarm and basic functions. Integrationg with WiFi via ESP32 for data sharing, maybe smart home automation. Different sensors for tracking enviroment data and sleep patterns.

Restart of project

• Change from arduino ide to platformio
• Refactor RTC functions
• Refactor display functions
• Refactor pages system
• Refactor bme280 sensors
• Add sleep mode
• Fix button design
• Add lights for the display

Documentation

Tools

• Bit map to code

Parts

• Display: probably E-Ink or 7-segment.
• Sensors: Microphone for noise, temperature, humidity, light.
• Actuators control: attach lights and motor to make waking up easier.
• Main controller: ESP32

Plans and ideas

• Theoretical idea
• Finding & ordering parts
  • Finding compatable parts
  • Making an order
• Testing parts and finding libraries
  • Display
    • E-Ink no touch 89x38cm - 296x128res 2.9" inch SPI
  • Sensors
    • Microphone Sound sensor wc
    • Enviroment bme280

  • Video?

Current progress

• fix main page
• fix weather page
• enter sleep mode
• add alarm
• test wifi provisioner
• add time sync
• hand move test
• docs
• presentation

problems met

• bitmap size containment
• system event configuration
• hardware and electronics problem
• usb charging
• compilation time
• interupts not fixed
• maybe e-ink wasn't the best idea

Settings and ideas

• There should be different wake up patterns for the alarm. For example - ring 1 second, wait 3-5 seconds, repeat.
• Extending the suspend button away, maybe using second ESP with ESP now protocol in deep sleep or unpowered.
• sync alarm with phone
• Weather forecast
