Learning about Arduino Microcontrollers

Made by: Zoey

Resistor 1 - Red,Black,Red,Gold

Resistor Value: 2000 Ω(ohms)

If you see Resistor 1's LED you may think this one is brighter than Resistor 3, but that is wrong because it has the most resistance, So the current that passes through should be the smallest.

Resistor 2 - Brown,Black,Red,Gold

Resistor Value: 1000 Ω(ohms)

This LED for Resistor 2 looks brighter than Resistor 1, There are changes, but not much, so if you do not see it carefully you may think this two are the same. It should not work like this Because the resistance values of resistor 1 and resistor 2 differ by 1000 ohms.

Resistor 3 - Yellow, Violet,Brown, Gold

Resistor Value: 470 Ω(ohms)

In this picture, you can see that the Resistor 3's LED is the least bright, But it shouldn't be like this because Resistor 3 has less resistance than the other two. So I think I do not take the picture correctly, The Resistor 1 and 2 is a different angle from Resistor 3. I may redo the experiment again.
