This disadvantage was that the lighting for each step could only snap on to full and off - fading was note possible. However, this was the agreed compromise to create the effect with the budget and resources available. | This disadvantage was that the lighting for each step could only snap on to full and off - fading was note possible.

A circuit had to be designed to allow the [[analogue control signal]] | A circuit had to be designed to allow the 0-10volt [[analogue control signal]] to power the relays that would turn each step's lamps on and off. The signal from the demultiplexer did not provide enough current to drive the relay coil nor enough to drive a transistor. | ||
