To be answered in your lab books as you explore: (include evidence, documentation, not just answers)
1) How is an LED different than a light bulb?
2) How do you hook up a DPDT switch so that it can reverse the direction of a motor? (Include a diagram of how you would hook a power source and motor up to such a switch)
3) How does a potentiometer work to control the speed of a motor? What do you think is inside? How do you hook one up? (Include a diagram) (Use a power transformer to power this)
4) Soldering (any hints recorded would be good)
5) Build a device that:
a) has an on/off switch with an indicator light
b) has a reversible direction switch with indicator lights and labels (clockwise, etc.)
c) Make sure that at least the switches have soldered connections.
d) Has a potentiometer that controls the speed of the motor
e) is decorated with light bulbs that don't vary in brightness as you control the speed of the motor.
f) Draw a diagram of the circuit (we'll probably do this later, but take notes in your book for later use.)
clean, easy to analyze wiring.
