GettingStarted

Well, in this part, you will get to know some basic concepts about SwiftIO with simple projects - like digital and analog signals. They are quite simple but are widely used.

Four simple projects with just several lines of code will guide you into the SwiftIO world.

• ​Blink - output 3.3 volts and 0 volts on a digital pin alternatively to blink the onboard LED.

• ​ReadDigitalInput - read and print the input value of a digital pin, either true or false.

• ​ReadAnalogInput - read and print the input voltage of an analog pin. The value is a float number between 0.0 and 3.3.

• ​PWMBrightnessControl - brighten and dim the led continuously by increasing and decreasing the duty cycle of the PWM output.
