A pattern for maintaining two separate GitHub identities on one machine (e.g. personal and work), with automatic switching based on which directory tree you are working in. No manual switching required after initial setup.

| The Adafruit 1.2" 4 digit 7-segment LED display with backpack (https://www.adafruit.com/product/1270) is connexted via the i2c bus interface. Adafruit has a quite good soldering & setup tutorial at https://learn.adafruit.com/adafruit-led-backpack/1-2-inch-7-segment-backpack, however they do a terrible job of describing in easy detail the necessary i2c writes to control the display from a language other than their provided libraries for Arduino or Python. So I've assembled a pretty comprehensive address and data to write in order to fully control the display. Please see attached images for some details. | |
