WeMos Flower Alarm Clock

thingiverse

This remix of M_I_A's Flower Alarm Clock includes new electronics and software. The clock uses a WeMos D1 R1 and gets the time via a NTP Server (Network Time Protocol). It supports the following features: Built in WiFi Hotspot to let users enter their WiFi credentials via their phone Over-The-Air software updating User selectable 12/24 hour time format User selectable display brightness (16 settings) Users can set alarm time, sound and whether the alarm is enabled Displays day of week, date and month Single 4 Digit display with flashing colon separator Video -------- https://youtu.be/8fWRf_Se8ks Display --------- Sourcing the Kingbright DC08-11EWA 0.8" 7 segment single digit displays used in M_I_A's clock proved difficult and way too expensive. I found a 4 Digit 0.8" display that fits perfectly. It simplifies the wiring and includes the colon LEDs. I got mine from eBay. https://www.ebay.com/itm/5pcs-0-8-4-digit-segment-led-displays-7-seg-with-clock-CC-CA-type-W-B-Y-G-R/143083815043?hash=item215075c083:m:mFxfQ8gLLKd56fv_4EyeObw 3D Printing ------------- I made a new back to hold a DC panel socket. This lets me use a standard 12V power brick. The rest of the files should be obtained from https://www.thingiverse.com/thing:3609703 PCB ---- Eagle files have been included. I made my board using the toner method. Except for the switches and LED display, all components are mounted on the back of the board. Software --------- The Arduino sketch has been included. I used the buttons in the following ways: SET - This now switches between various menu options - Alarm on/off, Alarm hours, Alarm minutes, Alarm tune, 12/24hr format, Display Brightness H - This becomes the UP button and alters the value or state of the above menu options M - This becomes the DOWN button and alters the value or state of the above menu options ALARM - This now changes the display to show the time, day of week, day/month and alarm time. All settings are held in EEPROM. Setting the timezone and daylight savings time --------------------------------------------- Line 166 of FlowerAlarmClockV3 contains a table that holds the time change rules for your time zone. For mine: TimeChangeRule aEDT = {"AEDT", First, Sun, Oct, 2, 660}; //UTC + 11 hours TimeChangeRule aEST = {"AEST", First, Sun, Apr, 3, 600}; //UTC + 10 hours Timezone ausET(aEDT, aEST); The table shows that daylight saving starts on the first Sunday in October at 2:00am (3.00am after change) and ends on the first Sunday in April at 3:00am. I have included other examples for US Eastern Time Zone (New York, Detroit) and Central European Time (Frankfurt, Paris).
