Usage


Hardware install

Note: Weight sensor output 0V when the load less than 150g,so we can not directly measure the load .My method is using a 200g local avoid measure blind spot.Read the analog data of 200g weight as no-load(0g),read the analog data of 700g weight as full load(500g).

Programming

void setup()
{
    Serial.begin(9600);
}

void loop()
{
    int value;
    value = analogRead(0);
    Serial.println(value);
}
