A display was added to this project since it seemed like a practical thing to include and because small displays are inexpensive. The one selected was a 16x2 character display with a daughter board so it could communicate with the I2C protocol and didn't require more than two I/O pins. Projects on this site have used the display before, but not a version with the daughter board.

Getting everything to work took longer than expected. All the components were taken out and an Arduino clone was swapped into the circuit to test if there was something wrong with the genuine Arduino. None of the libraries seemed to work, but some instructions on the Arduino forum eventually got the display to work.

Making the display work on available equipment

When the display was working, everything was reinstalled in the enclosure and tested with a battery. This was demonstrated on Episode 051 of Two Cyborgs and a Microphone. The most important thing was to follow all the OP's isntructions from the forum post. Although, an I2C scanner showed that the address of the display in this project matched the original documentation.
