The whole arduino thing is really new to me, so I’m pretty excited to do my first simple application, which is to make a circuit with parallel two Led, 3 switches and one linked with a resistor and the other linked with a changeable resistor. Which that you can control to let which color on, and change the lightness of the LED.
However I realized that my adafruit starter kit doesn’t contain a changeable resistor. So I replace the changeable resistor into a simple resistor.
What could be used as a switch. I came up with those below.
- A wire that connected and disconnected
- LED that connected positive and negative wrongly
I tried the first two of them, I found out that using pushbutton means to press it down still with your finger and let let go, just in order to let the circuit through, (??seems a little not logical to me)this seems like a lot of work since I’m going to have three switches. So I decided to use the method 1.
I used the red and green wire for the switch for the leds.
Try the switches.
and they works.
