  1. It is really useful to know what can go wrong with this kind of project. Thanks for sharing these chalenges, like tue switches assembled upside down. It happens all the time in the real world.

  2. Hey David, So…. I wrote an emulator for character LCDs. Then I added a photo-realistic, interactive example using your project box. Check it out here: https://visrealm.github.io/vrEmuLcd/examples/8bitguy
    For anyone interested, all the source code is there too.

  3. You actually had to mess up the connections with enable button as well, you should be setting enable low when you press the button and it should be high on default.
