the link will lead you to a PDF of my first electronics assignment. I think its alright, I feel like its too simplistic, especially since i completed A-Level physics, so this feels extremely simplistic compared to this, but dave seems to think its decent. Im very pleased with how the circuit turned out on the MyDAQ, since i've never used something like that before, except the linear potentiometer was too big in the resistance, so it only works over a very small distance. a potentiomer with resistance of approx 100 ohms would have been bang on. I've also added the video of the circuit in action. Enjoy!!
