This week I followed the initial ITP physical computing labs to get reacquainted with my Arduino and electronics. I have worked with an Arduino before and built projects that incorporated some medium level circuits. Therefore, most of these electronics labs were review. In the past, I have mainly used the multimeter to measure voltage so the way these labs used the multimeter was new. I can see how the multimeter can be used as a much more powerful tool in the future.
The following images highlight the circuits I made in the lab this week…
Once I completed the labs I made this felt fish with a switch and LED circuit (Figure 7).
I punctured an LED through the felt eye on the fish. I then created a switch circuit similar to the one seen in Figure 2. Here however, I used a conductive metal snap to make the switch (Figure 8). This way when the fin is up the switch is open and the light is off. When the snap is closed, the switch is closed and the LED turns on.
