Week 6 Progress Report

This week, we ordered 3:8 decoders and an Arduino starter kit for $3 and $37 respectively, not including shipping.

More wiring was completed. Specifically the inputs were processed in such a way that one of the four sets of inputs will be selected by the first 2 bits of the 5 bit selector and the other three bits will select which output of that decoder will be selected. After the signal comes out of the decoders it wll go into digital flip-flops, which will preserve state and then finally on to the transisters to allow power to pass to the PDLCD.

The layout for the clock was also drawn onto the ITO-coated plastic for etching next week. The layout leaves space for future wiring around the borders. In the right corner, there is a circle that will be the AM/PM indicator. The tens digit for the hours is a one-segment display followed by a seven-segment display for the hours' ones digit. The hours and minutes are separated by a colon, which will be two circles. On the right of the colon, there are two seven-segment displays, one each for the minutes' tens and ones digits.
