Thank you so much, I'm receiving data here, but now I have to work in how to put the numbers togheter to form a int number to flash a led

Ok I tried SO MANY times, but I can't!

Look: I received data and transformed it to a String. Now I can't convert it to int to analogWrite and LED.
I tried like it too:
   for (i = 0; i < buflen; i++) {
       var = char(buf);
          int a = atoi(var);

But I can't :(

Could somebody help me?

Sorry by asking so many times, I'm not lazy, but I really got not results doing this, if somebody helps me I can understand, like the transmitter code...



you must atoi the whole buffer at once ... assuming there is only one number in the buf

Code: [Select]

char buf[20] = "123";

void setup()

Atleast 100 ohms and 220-2.2K is recommended.
Avoid throwing electronics out as you or someone else might need them for parts or use.
Solid state rectifiers are the only REAL rectifiers.
Resistors for LEDS!
