Ok.. 'Sometime after' meaning still within my loop. Would I make this an if statement or can I go ahead and write my constraint from the read function? See below.
void loop(){
if(Serial.available())
motorForward();
motorBackward();
if(Serial.read()){
for(int=0; i<=n; i++) //accel. Motor from 0 to 255
{ analogWrite(pwmB, i);
analogWrite(pwmA, i);
delay(10);}
}
