Day 4 of Mechatronics

Today we were given an introduction to Auduinos and a basic "how to". We watched a lengthy youtube video and dicussed any questions and final points on the subject. However, since I was behind on labs I did not have time to get to use the Auduinos as of yet. So seen here in figures 1 is the Auduino I intend to use for future labs.

Transistor Labs:

Figure 2. Our first transistor set up with a push switch

Since the transistors in our class is not quite enough for everyone to use while anticipating the number of broken transistors as a result of this lab. So for this time we worked with partners. The first of the two labs we simply had to set up a circuit to light an LED with a transistor among the components we had to use as well as a push switch as seen in Fig 2.

Next, we removed the switch to use our finger to complete the circuit since our finger would have enough resistance to maintain the circuit without burning out the transistor as seen in Fig 3.

Figure 3. Same set up but without a push switch and our
fingers were the resistor.
