| http://www.w3.org/ns/prov#value | - in your code you need to check this value e.g. once per hour or sosome code inspiration Code: [Select]unsigned long previous = 0;void loop(){ if (millis() - previous > (3600L * 1000L)) // or other timing previous = millis(); { int voltage = analogRead(A0) * 12 * somefactor /1024; // somefactor to be determined // write to display if (voltage < 10 ) { // alarm!!! } } // additional things here}
