// 05 - servo motor v2.swift4a
// Swift For Arduino
// This code is for project 05 of the Arduino Starter Kit (called mood cue)
// It uses 1 potentiometer, 1 servo motor with a motor arm and 2 100µF capacitors
// The potentiometer is read, and the servo is positioned according to potentiometer value
// There are two constants (minimumPulseWidth and maximumPulseWidth) which can be adjusted
// depending on the servo used. The values given are for the servo SM-S2309S

Blink

← Introduction to S4A

The first thing to try to get started is a very simple program that doesn't require the breadboard. There is a built-in LED on the Arduino UNO board that is connected to pin 13. To learn more about the digital pins of the Arduino UNO, there are details on the UNO web page. Select the FAQ tab and scroll down to the Input and Output section for example to see the following information:

LED: 13. There is a built-in LED driven by digital pin 13. When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.

We can make this LED blink with the following code.

Programming the Arduino UNO with Swift For Arduino

This is an introduction to programming a Arduino UNO board with the Swift For Arduino IDE.

In the Arduino IDE, programs are structured with two main functions:

void setup(){
    
}
