Description
Word clock made with neo pixels, arduino nano, tiny GPS and a RTC (ds1307)
Dose require a large wide bed to print,
neopixels 60 per meter fit perfectly behind each letter.
If you have a CNC use the no front 3D prints and CNC out of 3mm perspects using the CNC letter.tap,
use perspects colour of you choice, i use black as it give a nice mirror finish when you use smooked black perspects in front of it.
button on side is used to change colour but this is done every hour, and a quick double tap will show the date.
On the Nano pin A3,A4,A5 connect to the RTC, pin 6 is to the neo pixels, pin 5 is the button, pin 7,8 is serial for GPS and 9 is for the power on of GPS(only there for rebooting the GPS so is not required for it to work, GPS can but feed off 5v directly)
On boot the display will cycle through every colour on every neopixel, then while it is waiting for signal it will go into a matrix show, the matric show also shows for 1 min at 1 min past the hour,
on the hour the date is desplayed first showing the day then the month then the year.
if you do not wish to use a picture frame, a 3mm sheet of perspects on the front looks quite good.
i am not a programer or and cad expert this is my take on the word clock, i am looking to do a WIFi version as a few friend live in flats and getting a GPS signal is very difficult
i have added the wifi verion, it uses a wemos d1 mini or equvlant. still uses a rtc and the pins are unchanged except there is no need forthe GPS reciver,
when you first boot you need to hold down the button on power up, this enables the use of the EPPROM (to store your wifi details so if you unplug it or losses power it will auto reconnect when it next gets powered up) and start the clock as a wifi access point, connect to it with your phone or pc(WIFI hotspot called "Word Clock") ,then in a web browser go to IP address 1.1.1.1, enter in your wifi details and save. if you ever need to clear and start again hold down the button at power up and it will wipe your details and start the access point ready for the new ones.
the clock will now connect to your home wifi and get the time and date from 'time.nist.gov'.
you may need to change the time zone to your local timezone if you are not in the UK.
