Can someone look at this code and tell me if I'm on the right track? I'm trying to scroll the temp. and time. I don't know how to add the degress symbol and colon in their proper places. Thanks and I appreciate your help.
int DataPin = 9;
int LatchPin = 11;
int ClockPin = 10;
int clock = 13;
int Reset = 12;
//x,y for the loop
int x;
int y;
int sensorPin = 0; //the analog pin the TMP36's Vout (sense) pin is connected to
int adjust = -11;
