grovepi/Projects/Holidays_Wreath/README.md

This folder contains the code to create a smart Holidays wreath, using a string of holiday lights from yesteryear. The wreath lights will turn on when it's dark and wait for sunrise to turn off. The lights will blink whenever a movement is detected, whether it's day or not.

Use:

• the PIR sensor on port D8,
• the light sensor on port A0
• and the relay on port D2
