| The brightness is almost as bright as the on with resistor 2 which is weird becuase resistor 2 has a greater resistor value and the bulb connected to resistor 2 should be less bright compared to this bulb. Again, it may be becuase I did not connect the wires properly on this circuit which resulted on the electricity not flowing properly. | The brightness is almost as bright as the on with resistor 2 which is weird becuase resistor 2 has a greater resistor value and the bulb connected to resistor 2 should be less bright compared to this bulb.

| The resistor controls the blinking speed because, the resistor controls speed the capacitor charges at. If the charging of capacitor slows down, the LED will need more time before it can turn on. I can add resistance by adding a resistor with greater resistance and doing that would slow down the current. To change the amount of resistance without swapping out parts, I can use a potentiometer. | The resistor controls the blinking speed because, the resistor controls speed the capacitor charges at.

| + | ===== Resistor Calculator ===== | ||
| + | This resistor calculator can help you find a resistor based on the colors, it can also search for a resistor in the resistors database you will be able to log into. You can also give it a number. With it, it will give you what the numbers equal to and find a resistor that in your database that matches your number. If there are not exact matches, it will find one that is closest. It all can be done with a quick way that you can enter numbers and a user interface that tells you everything that you need to know: | ||
