1. LEDs/ SSD
2. The purpose of this lab was to simulate several led
designs and simulations by using a bread board, leds, and several other
components to become familar with arduino. Similarly we were able to
learn more about the Arduino code. In the same manner, we were able to
use the Arduino interface to display numbers using an SSD. To begin we
used many wires to connect each led, then we were able to simplify the
amout of wires to 3 and then just one output for several SSDs.

Figure 1. Demonstration of all nessasary tasks for LEDs and Arduino are
shown.
Figure 2. Figure 8 Shown demonstrating the individual wiring.

powered by THREE wires showing several examples of manually placing
wires to achieve numbers
Figure 5. SSD single wire powering up SSD display shown with MSB and
LSB (simlar demonstration because hex values were changed accordingly)
The values are either being picked up from the most signifcant bit or
least depending on minor code change.

Discussion
The use of the ardiuno uno is helpful in further understanding the
logic and code that arduino operates. The led simulations help to
further understand the code. The SDD demonstrations allows the user to
wire up all connections by hand, which is valuable, and can achieve a
cool result in the end. Overall Arduino is a helpful tool and it is
aimed to learn more.
