Hello fellow arduino enthusiasts.
I am completely new to arduino and whats worse, completely new to electronics. I am trying to catch up on all I have missed in physics class back then, but I am not there yet.
I need to build something for my sister and for that, I need to control 4 or 5 RGB LEDs. They should all show the same color, which seems fairly easy. Unfortunately, it has to be possible to switch off single or multiple LEDs altogether, while the rest stays on. How would I be able to achieve this (problably rather easy) task?
Hello Hackscribble,
the LED will change their color. When a button is pressed, one LED will turn off and all others will change to a different color. The button is pressed again and another LED goes off, making all others switch color again. Another switch will turn one LED on and revert the color.
I hope the way I described it makes it understandable

Hi S0ul01, no please try again. How many buttons are there? Are they simple pushbuttons? Does pressing the same button cause 1 more led to switch off each time (as well as change the colour of the remaining leds) until all leds are off?
How many colours do you want? Will 7 colors (red, green, blue, yellow, cyan, magenta and white) be enough?
Have you purchased the leds yet? If so, are they common anode or common cathode?
How bright must the leds be? (please do not say "as bright as possible") Will they be used indoors, outdoors, in sunlight, only in the dark or dim lighting?
