Using E-paper with the Arduino
A sketch for the EPA20-A
Electronic paper — a.k.a. e-paper — is an unusual type of display. Once a picture (or text) is displayed, no further energy is required to maintain the display. Energy is only required to change the display. This is very useful in applications where the amount of available energy is limited. In this article we describe a practical application of such a display and control it with an Arduino/Elektor Uno.
Build This Project
