fading rgb led (arduino)
It can be used as a good night light or mood lighting.
To do this, you need :-an Arduino (
I am using Arduino UNO R3 but others can use it as well)-an RGB Led (
I use a common anode, and the common cathode can also be used)-a Breadboard-some wire-
2 resistors 180 ohms (
Brown, gray, brown, gold)-
1 Resistance 330 ohms (
Orange, brown, gold)
The schematic diagram is simple.
If you have a co-melt anode led (like i do)
If you have a co-cathode led, just connect it to 5 v.
Connect the other 3 leads to the 3 PWM pins on the arduino with a resistor (
Value depends on led).
The code is a bit difficult but quite simple.
This code is only for co-anode LEDs.
If you want to use it for a co-cathode LEDs, you have to change all the \"analogy\" lines to \"analogy \"(
So it should work (
I have not tested).
