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. 


3. Materials and Methods

Wires/ Switches/ logic gates
SSD/LEDS
Arduino UNO/ Arduino Program


4. Results


Figure 1. Demonstration of all nessasary tasks for LEDs and Arduino are shown.


Figure 2. Figure 8 Shown demonstrating the individual wiring.


Figure 3. Figure 6 shown to demonstrate indivual wiring of SSD.
















Figure 4-12. SSD 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.


Figure 6. 2020 displayed using the 4 panel SDD display.


Figure 7. Closer look at 2020.


Figure 8.  Hold down becomes 1 second blinking let off and becomes 4 times a second code.



5. 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.
