Process:
At the very first beginning, I looked at the schematic carefully. However, I found out that I was not able to recognize all the component symbols on the schematic, therefore, I referred to the reference at the bottom of the web page to let myself be familiar with them first. Then, I started to aligned all the real components with their symbols one by one. After all of this preparation work has been done, I began to figure out the electricity flow in the three circuits. Later on, I experimented a few times to find out where to put the components that may be the clearest and easiest way(although I do not think that I found the simplest way). And I tried to put every component and used it to wire to connect them together as the schematics instructed. After finishing the circuit, I used the power to charge it and check if it works. I met with some troubles with the first one, and the LED did not turn on after I press the button. But I could not figure out why by myself so I asked the fellow for help. She told me that since the button has four ends, it would be better to put the button in the center, crossing the two halves of the breadboard. Finally, I was able to finish the first task. Moreover, since the three tasks are quite alike actually, so I finished the whole three tasks soon after I figured out the first one.
Components:
- Resistor: Usually we use the 220-ohm ones or the 10k ohm ones. It is used for reducing the voltage the LED or other components will gain in the circuit.
- LED: can be seen as a kind of output; lights
- Capacitor: store the voltage or power
- Voltage Regulator: regulate/adjust the output’s voltage
- Variable Resister/Potentiometer: similar to the resistor, but the extent of the voltage reduction can be altered
- Push Button: switch; to collect the input information and control the output status
- Speaker: making sounds
Reflection:
When making the first circuit, I encountered several obstacles. One is that I have not used these Physics knowledge about electricity for a really long time. So I needed some time to get myself re-familiar with this knowledge. The other is that my button did not work because the button has four ends but I put all of them in a connected area, which is more carefully illustrated in the first paragraph.
