Circuitry

So after last class I was given this circuit starter kit to mess around with. It comes with a book that teaches you all the basics about circuitry and also introduces you to the physics behind it. I don't know much about circuitry at all so I could have said some incorrect things in the video. This it looks pretty fun and can really teach you how to utilize these basic components to control many different things. The one thing I want to learn is how to use a transistor. The transistor is suppose to act as a circuit controller for analog devices such as a motor or a buzzer. The transistor I believe has an input for the electrical current for the analog device and an input for the digital electrical current (9v in this case) which acts as a trigger for the analog device. It looks pretty interesting and fun to mess around with, maybe we can utilize a transistor and other components to control something on stage.
