Tell us about yourself!
Hallo Jan, I have build a dutch wordclock myself (because i am dutch) with an ESP8266, but am looking for improvements. The Rainbow effect is very nice.Did you thought of using an ESP32 instead of a Mega with extensions? (ESP32 has them all onboard & is cheap nowadays)
I found one, & after some emails with the nice people who made it i was able to make my own. So the efforts should go to the 2 dutch makers. They even implemented a weatherclock in it.https://bitbucket.org/vdham/wordclock/overviewA week after finishing, i uploaded another code to my clock based on this one, which was made by a friend of them, this time compact coded with the FastLed library. When i switch it on, it has a rainbow effect. Until wifi signal is found the 4 dots on the bottom keep flashing red. When it has signal it becomes green. (or any other colour you want its adaptable in the code) If you want to know more just ask me.
Tinker thanks for the compliment.
I did find one in dutch & made it, looks great on the wall. But thanks for all the effort.
I was going mad, until i read this article Step 5So simple, but... you gotta know it.Thanks man.
Conclusion & Going Further
Nice project, i'm testing the ws2812 around an old LP, only an LP is slighty to small for 60 leds. Maybe i mount it on the back of my oldskool clock with roman figures which already hangs here, combining the two, this way i only need to make a frame for the leds & glue the arduino & ds3231 on the back.
