-=====Learning about Resistor and LED===== +=====Learn how the breadboard and switch works=====
-===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.+====breadboard==== 
 +**each row is concatenated, Which means that A to E in the first line are all connected together and so on.**
  
-{{:zoey-resistors_1.jpg?400|}}+**There are two lines next to it, one red and one blue. The red one is connected positive, the blue one is connected negative.**
  
-===Resistor 2 - Brown,Black,Red,Gold=== +{{:zoey-breadboard.jpg?400|}}
-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. +photo from [[https://www.digikey.tw/zh/maker/projects/learn-to-breadboard/43bde9f32dad493182278f0441466a6e]]
  
-{{:zoey-resistors_2.jpg?400|}}+====switch==== 
 +**The yellow box means, The electricity will go through**
  
-===Resistor 3 - Yellow, Violet,Brown, Gold=== +{{:zoey-how_the_switch_works.svg?400|}}
-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. +====two LEDs alternating according to a switch(resistor: 470)==== 
-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.+<html>

-{{:zoey-resistors_3.jpg?400|}}+=====Learning about audio oscillator and amplifier===== 
 +====Oscillator with Potentiometers==== 
 +If the potentiometer resistance is getting smaller the capacitors charge faster so the oscillator frequency will be faster because more current flows. The opposite of if the potentiometer resistance is getting bigger, The representative said that the charging speed of the capacitor is relatively slow, so then the oscillator frequency will be slower.
