Knight Rider
This Project was created by Frazer Fyfe, Mark McGowan, Christine Orr and Lynn Wiseman
Concept
For our project we decided to replicate the light sequence from Kit, The Knight Rider car. The lights flash in a linear sequence from left to right, and then back again.
We decided that it was very likely, when in a PLX role we would buy a Maplin kit to create this effect, as their are time constraints. We decided upon a Velleman MK107 LED Running Light Kit. (See Photo 2 and 3)
The Kit consists of 8 Led's which have a changeable speed and pattern.
At the centre of this circuit is a CD4015 Dual 4-bit Shift Register
A shift register contains various storage locations and during each clock cycle the data stored in each register is moved along the chain to the next register. This process continues until the cycle is complete. This is displayed in the diagram.
This is what causes the LED's to light up sequentially and in turn follow a pattern.
Problems
Unfortunately we were unable to make the sequence run in reverse. We now know that in order to do this we could heve connected the LED's in pairs. By doing this one input from the shift register would light the LED's in the first sequence, and the other connection would light them on the return.
We also tried to recreate the voice recognition monitor from the interior of the car.
We attempted to do this using an LED Sound to Light Unit. (See Pictures 4, 5 and 6) Unfortunately, due to faulty soldering we were unable to demonstrate this in class.
