  Well it is finished!

  I have uploaded a schematic and shortly will upload the sketch and if I can a short video!

  To use:

  You input 7 bit's of a byte (the first bit is always zero - 7 bit ascii). Essentially the bottom right will blink either a zero or a 1. When the bit you want is shown, push the button and the bit will be added to the byte being collected. When you have a full byte, it is sent out on pin D8 - any input comes in on pin D9 (I may have these reversed). As I am just using this for loopback, Instead of SoftwareSerial, I had to use AltsoftSerial which allows full duplex TX/RX.

  What you send appears on the top line and what is received comes back on the line under that. Special characters are decoded to <SI> <CR> etc.

  It works - and will teach you binary - but I STRONGLY suggest a ascii/binary chart will be needed in the early stages.

  As I say - completely useless - but does work!

  FInally got time to do some more work. (Wife was working a late shift). Got the actual keyboard working now entering 7 bit binary and displaying actual ascii (including special character codes).

  Todo:

  1. Link to Raspberry pi echo program.

  2. Display sent/received data

  3. Minor fix for the 'do I want this character or not.

  4. Schematics and doco.

  This was on Anzac day - wife was at work.

  Plugged in brand new nano into Mac.

  Mac paniced!

  Lots of screwing around with CH340 drivers but eventually got it going.

  Downloaded basic test - Blink ** Passed**

  Wired up Oled and tested **Passed**

  Wired up button and did some basic tests **Passed**

  Started writing code - working fairly well - but still some minor bugs.

  TODO.

  Chase bugs down.

  Link to Raspberry pi serial port for basic echo test

  Take pictures and upload

  Produce schematic and upload

  Upload sketch
