Have you worked through any of the examples provided in the IDE?

Yes some of theme, but i i need learn more, think its so difficult.

int Led = 5;
int switch1 = 7;
int switch2 =8;
void setup() {
pinMode(5,OUTPUT);
pinMode(7,INPUT_PULLUP);
pinMode(8,INPUT_PULLUP);
}

void loop() {
if(digitalRead(7) == LOW) Led--;
if(Led < 0) Led = 5;
if(digitalRead(8) == LOW) Led++;
if(Led > 255) Led = 255;
analogWrite(5, Led);
delay(30)

i did this one for fade, but now how to turn it on and off, with the switches

Please use code tags.

Using appropriate variable and constant names will help you figure out what's wrong.
Use 'const int ledPin = 5' and 'int brightness = 0' for example.

You probably mean: 'if(Led < 0) Led = 0;'

You declared variables for input pins, but you didn't use them. Also, they should be constants.
