Here's what I have =
const int buttonPin = 5;
const int TxPin = 0;
const int RxPin = 1;
// variables will change:
int buttonState = 0;
void setup() {
pinMode(buttonPin, INPUT);
}
void loop(){
buttonState = digitalRead(buttonPin);
if (buttonState == HIGH) {
Serial.write(TxPin,45;
}
else {
digitalWrite(TxPin, LOW);
}
}
const int ledPin = 7;
const int TxPin = 0;
const int RxPin = 1;
void setup() {
pinMode(ledPin, OUTPUT);
}
void loop(){
if (Serial.println("45")LedPin == HIGH) {
}
else {
Serial.pintln("45")(ledPin, LOW);
}
}
