Hey, I received the SIK version 4.0 which included the SIK guide v4.0a. I noticed in the Instructors Notebook that we are supposed to be using the SIK guide version 3.3 and also read in a recent post from another student that they were also using the SIK v3.3, but it looks like both version are somewhat different.

Here are some of the differences in the components that were included: Version 4.0 has 2 gear motors and an ultrasonic sensor where as version 3.3 says the kit comes with 1 DC motor,  diode, transistor, flex sensor, soft potetiometer and some otehr devices. There are many other differences as well between the two versions; The circuits are numbered 1 through 16 in the SIK v3.3 where the 16th circuit is the simon says game. In the SIK v4.0a there are "projects" 1 through 5 and each project has circuits 1A, 1B & 1C etc. with Project 2, circuit 2C being the "Simon says" game. It looks like if I am to use the SIK v3.3 guide then I may need extra components to complete some of the more advanced circuits.

Was anyone else confused about this too? I ended up getting pretty far using the 4.0a guide, since it came with my kit, and now I feel like I wasted a bunch of time and have to start from scratch, knowing that I may not be able to complete some of the circuits from the SIK v3.3 guide. I wouldn't be surprised if I'm mistaken though. 

Anyways let me know what everyone else thinks on this? Any feedback is appreciated.
