Motorbike Gear Position With Seven Segment Display

This is project involves decoding a number of inputs (in this case 7) to display as numerical values on a Seven Segment Display (SSD) using something called Binary Coded Decimal (BCD), a Diode Matrix and a micro-chip called a BCD4511 (or CD4511). I had a very steep learning curve with this project and I explored a whole number of different options which proved to be either imposible, useless, too sensitive for what I need. I found this solution to be fairly elegant and I wanted to collate all of the useful info I gathered during my searching so that others may have an easier job at doing the same.”
