Hi I had a problem with reading int - kept reading them as decimals!
So I figured I would read the numbers as chars and then convert them with atoi!
I told me a had to us
char * g;
instead of:
char g;
in order to use atoi();
but the following didnt work:
char * char1;
char1 = Serial.read();
WHAT SHOULD I DO
Any help will be appriciated

char * char1;
char1 = Serial.read();

This didn't work because you can't assign an int to a char pointer.

so how can I read a value and assign it to a char *?

You can't assign a value to a char pointer like that.
You assign the value to what the pointer points to, but first you need to make sure the pointer points to something.

Try something like this:

void loop() {
  int c;
  static int the_number = 0;

   if (Serial.available() > 0) {
      c = Serial.read();
      if (c >= '0' && c <= '9') {
        the_number = 10 * the_number + c - '0';
      } else {
         Serial.print("the number is ");
         Serial.println(the_number);
         the_number = 0;
      }
   }
}
