At last the PCBs for this project have arrived so now the project can proceed to a successful conclusion.
The PCBs are the same width as the 4inch seven segment LED modules with a matching plug and socket on each side. The idea here is that a series of modules can be assembled into a row by plug-and-play. This perfectly matches the ‘daisy-chaining’ circuit architecture.
The first seven segment module in the series uses optical isolation on all of its digital inputs. This is to eliminate any risk of circuit damage or circuit malfunction due to transient noise pick-up or ground loop noise.
I plan to use this new large scale and modular display in conjunction with under track sensors to calculate and display vehicle speed as well ID read-out.
A simple but fun project.
