This lab was fun and relatively easy to do. We didn't have a traditional diode, so we used an LED (the cathode connects to ground and the anode connects to the transistor ) to direct current towards the transistor. We positioned the diode in parallel with the collector and emitter as shown below. We also used a potentiometer to control the speed in which the DC motor operated. In the lab below, we will use an H Bridge to control the direction of the DC motor's operation.
With the H Bridge Lab, I didn't have a switch so we used a button that when held down, would change the direction of the DC motor. We helped to visualize this by putting a piece of tape around the motor's end so that when the change in direction occurs, it is more visible.
We decided to add an additional motor and to add a LED to each in parallel so that when our switch is activated one motor changes direction and its corresponding LED lights up.
