Tomorrow I'll play around with it. Remember I told you I am not a programmer type, I just play around with the stuff because it keeps my brain doing something in old age. I do know when we tell a pin to go High it will remain there till we tell it different. Something does come to mind. Usually with motors or a model car we have a standard motor FWD and REV and another motor for steering Left and Right. Normally a button is held and the motor runs as long as the button is held. Crudely put but close to what's happening. We can toss in a throttle for motor speed and get more complex but crude and simple is good for now.Would adding "LOW" statement to the next else if do?
Ex:
If(t =='F') {
DigitalWrite (13, HIGH);
}
Else if(t == 'B'){
DigitalWrite(13, LOW);
DigitalWrite(12, HIGH);
}
Using communications like we are is a different animal. I am sure someone good with this stuff could just bang the code out but me? I need to think about it.
