Tell us about yourself!
It can be done using loops. For example - for fading or moving effect.. let all CA be high, then creating a loop and providing a condition such that it can be looped as many times as we want. Let's take a counter initialise at 0 till it's less or equal to 10 continue. Statement in the block would be CC0 to CC4 one by one after giving some delay will get high. If CC are high then LEDs won't glow of that layer and thus due to the looping and time delays we will get a fading effect or can say animation or moving effectThere are many ways, this is one of them, basic and simplest.
THANK you so much ! :)
Those are optional. Maximum I/O current for Arduino is about 45mA and for LED diode of 5mm 2V forward rated current is 20mA. Since these are maximum values, it's nothing to worry about getting LEDs blowing up but for being on safer side resistor are used to limit current. Resistor are connected in series between Arduino and wire connections of LED cube to it. THANK YOU FOR ASKING !!!
