Analog Input and Output

This example shows how to receive analog input and give output in wave form via the arduino our code will perform the following opertions.

Disabling watchdog.
Creates a array object consisting of all the pins.
Executing infinite loop for read and write continuously through the I/O pins.
In the loop, Take input into the zeroth analog pin.
Make the input value ready to be sent through a digital pin.
Give output from the 13th digital pin.
All these steps are implemented in just few lines of code

pub fn main() {
    
    let watchdog = unsafe { WatchDog::new() };
    watchdog.disable();

    let mut pins = Pins::new();

    loop {
        
        let a: u32 = pins.analog[0].read();

        let b: u8 = map(a as u64, 0, 255, 0, 1023) as u8;

        rustduino::delay::delay_ms(1000);

        pins.digital[13].write(b);

        rustduino::delay::delay_ms(1000);
    }
}
