Arduino Start Template

Lets get started with arduino.

Simple setup for the following components

1. Move a servo
2. Read an input (button/sensor)
3. Digital output (LED/Relay)
4. Debugging
5. Run a slow timer

Overview

Setup

void setup(){
//Define all sensors
}

Fast loop (200 ms delay)

void loop(){

  //Do some stuff

  delay(200);
}

Simple slow loop (inside void loop(){})

if (millis() - timeStamp >= 2000){
  //Do some stuff
  timeStamp = millis();
}

Servos

A servo can be controlled with the help of the Arduinos servo library.

Include and define

#include <Servo.h>
Servo myservo;  // create servo object to control a servo

Attach servo (in setup)

myservo.attach(servoPin);

Move servo (0 - 180 degrees)

myservo.write(123);

Analog Read

Reading of voltage input can be done with analogRead()/digtalRead()

Define in setup()

pinMode(sensorPin,INPUT);

Read analog value of sensor in loop()

int sensor = analogRead(sensorPin);   =>  0 - 1024

Digital output

Switch output voltage between 0 and 5 V on pins.

Define in setup()

pinMode(relayPin,OUTPUT);

Set inside loop()

digitalWrite(relayPin,HIGH);

Debugging

Use the comport and IDE console to debug your Arduino

Define helpfunction for messages

void sendDebugVariable(String title,int value){
  Serial.print(title);
  Serial.print(" : ");
  Serial.println(value);
}

Send debug command

sendDebugVariable("Button",buttonPinValue);
