eInkCalendarWithHitokoto eInk Calendar with Hitokoto and To do List

中文

Onse upon a time...

A year befor I had had to stay at home for Online-Classing, and it was very boring. Then I saw a project on OshwHub ESP8266 eInk Clock. So I made one and added English words list in the flash.

At the same time I saw an eInk device in Xiaomi Store 有品&秒秒测智能健康日历. I am eager to make the same product.

Eventually, I found a repositorybreakstring/eInkCalendarOfToxicSoul.

Just do it.
