I acquired an InkShield from this Kickstarter. My goal for this project is to have a smallish enclosure to contain the system and buttons on the top which allow different messages to be printed.
I am banging together the inkshield sample code with OneAnalogPin5switches code. To update the messages printed I intend to write a new sketch to the arduino with new values for the buttons. One could write a serial menu interface to store messages in flash, but that is way down the road. Code will be posted once it's working.
