Another set of eBay purchases provided an ESP01, blue board and 12 LED ring. This page allows some prototyping a display idea that can be used in an Python sketch.

# main.py - save to ESP01 so it boots this on power up.

# NOTE: ESP01 outputs debug on boot and this causes the LED ring to flash bright.

The LED ring has 12 LED, turn the LED on bases on the Hours minutes and seconds
Create 12 LED with own ID, spaced in a ring.
