Hi Folks,

I've added some components and files to this project that I used to speed up the whole Screen Blink to Microcontroller communications. There might be some remnants from all my testing that are no longer required.

I changed the "protocol" from I2C to what I'm calling TwoWire. I'm sending 8 bits at a time, MSB first (makes it easier to see what data was send on a scope or logic analyzer), with a small delay between bytes.

Any comments/suggestions/corrections/money will be appreciated ;-)

I forgot to mention that in the Fritzing diagram, I couldn't find the photodiode sensor and used an IR distance sensor that looks almost identical to the photodiode sensor. The exceptions are this is only one photodiode (without the IR transmitter) and the photodiode sensor has four pins: 1) Vcc, 2) GND, 3) DO (Data Out) and 4) AO (Analog Out). Pin 4 is not used in this case.
