i want to combine them in one sketch

Using Arduino Programming Questions
#1

Hi all,

this is my first time at working with the Arduino and im loving it.

Im just having trouble at trying to run several things at the same time.

I have two sketches, sinewave aand trianglewave progams and i want to combine them in one sketch. so i can choose one of them for output.

That’s OK - you don’t need to ask permission.

Several things at the same time:https://forum.arduino.cc/index.php?topic=223286.0

holdingpattern:
In general, stick the code in 2x functions say doSine() and do(Triangle), and call either of them from loop() according to a switch?

That's easy. Code it and come back if you have any problems. It's only when you have to make many things happen at the same time, that you need the approach that I linked to.

I would use more descriptive label than doSomething()... like displaySine or showSine etc...

If you want to display a triangle and a sine at the same time, that is a completely different story.

I tried combining these two sketches but the two sensors are competing with each other. How can I solve this problem?

This is the code for the smoke sensor:
#include <TFT.h>

int smokeA0 = A0;

int sensorThres = 200;

void setup () {
pinMode (smokeA0, INPUT);
pinMode (13, OUTPUT);
Serial.begin(9600);
}

void loop() {
int analogSensor = analogRead(smokeA0);

Serial.print("PinA0: ");
Serial.println(analogSensor);

if (analogSensor > sensorThres)
{
digitalWrite(13,HIGH);
delay(50);
digitalWrite(13,LOW);
delay(50);;
tone(8,1000,1000);
}
}

This is the code for the Human Touch Sensor with servo motor

const int servoPin = 7;
const int touchPin = 10;
int angle =80;
int angleStep =10;

#include <Servo.h>

Servo myservo;
void setup() {
Serial.begin(9600);
myservo.attach(7);
pinMode(servoPin, OUTPUT);
pinMode(touchPin, INPUT);
Serial.println();
}

void loop() {
while(digitalRead(2) == LOW){

int touchState = digitalRead(touchPin);

if (touchState == HIGH) {
angle = angle + angleStep;

if (angle <= 0 || angle >= 180) {
angleStep = -angleStep;
}
myservo.write(angle);
Serial.print(“Moved to: “);
Serial.print(angle);
Serial.println(” degree”);
delay(10);
}

}
}

And this is what I come up when I combined this two sketches:
#include <TFT.h>

int smokeA0 = A0;

int sensorThres = 200;

const int servoPin = 7;
const int touchPin = 10;
int angle =80;
int angleStep =10;

#include <Servo.h>

Servo myservo;

void setup () {
pinMode (smokeA0, INPUT);
pinMode (13, OUTPUT);
Serial.begin(9600);
{
myservo.attach(7);
pinMode(servoPin, OUTPUT);
pinMode(touchPin, INPUT);
Serial.println();
}
}
void loop() {
int analogSensor = analogRead(smokeA0);
Serial.print("PinA0: ");
Serial.println(analogSensor);

if (analogSensor > sensorThres)
{
digitalWrite(13,HIGH);
delay(50);
digitalWrite(13,LOW);
delay(50);;
tone(8,1000,1000);
}
{
int touchState = digitalRead(touchPin);
if (touchState == HIGH) {
angle = angle + angleStep;

if (angle <= 0 || angle >= 180) {
angleStep = -angleStep;
}
myservo.write(angle);
Serial.print(“Moved to: “);
Serial.print(angle);
Serial.println(” degree”);
delay(10);
}
}
}
