Well, in this part, you will get to know some basic concepts about SwiftIO with simple projects - like digital and analog signal. 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 volt 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.
