Analog Read Serial ​

This is the smallest example for WARDuino, the program shows how to read analog input from the physical world, and print it out via the serial bus.

Circuit ​

We can connect a potentiometer or similar sensor to one of the I/O pins of the embedded device. With WARDuino you can measure the resistance produced by the potentiometer.

For this example you require:

1. A microcontroller
2. Potentiometer or other sensor

Program ​

Read a sensor, print its state out to the serial bus.

import {analogRead, delay, print} from "as-warduino/assembly";

export function main(): void {
    const value = analogRead(13);
    print(value);
    delay(1);
}

use warduino::{analog_read, delay, print};

#[no_mangle]
pub fn main() {
    let value: u32 = analog_read(13);
    print(value);
    delay(1);
}
