I'd like to support the value of temperature from Thermistor with Arduino Mega and Ramps 1.4
but without using any Firmware like Merlin.
Right now I use the follow code and all feature works well but I find not correct PIN
for T0 thermistor.
void loop () {
if(Serial.available()){
val = Serial.readString();
}
if (val=="ON"){
// FAN anschalten
digitalWrite(FAN_PIN, HIGH);
}
else if(val=="OFF")
{
digitalWrite(FAN_PIN, LOW);
}
// Temperatur anschalten
digitalWrite(HEATER_0_PIN, LOW);
// MOTOR
// LOW=Uhrzeigersinn - HIGH=Gegenuhrzeigersinn
digitalWrite(E_DIR_PIN, LOW);
for (int i = 0; i < 200; i++)
{
digitalWrite(E_STEP_PIN, HIGH); // Motor an
digitalWrite(LED_PIN, HIGH);
delayMicroseconds(5000); // 100=sehr schnell bis 5000=sehr langsam
digitalWrite(E_STEP_PIN, LOW); // Motor aus
digitalWrite(LED_PIN, LOW);
delayMicroseconds(5000);
}
delay(1000);
}
