He estado trabajando en este programa para un controlador simple. Tengo un prototipo completamente conectado y funcionando, sin embargo, el pulsador momentáneo no es muy confiable. A veces lo lee y otras veces lo ignora.
Aquí está mi código.

*/
#include <math.h>
int feedValve = 12; // feed valve is connected to pin 12
int returnValve = 11; // return valve is connected to pin 11
int heater = 10; // heater is connected to pin 10
//int loopValves = 9 // loop valves are connected to pin 9
//int pump = 8 // pump is connected to pin 8
int button = 2; // button is connected to pin 2
int val; // variable for reading the pin status
int val2; // variable for reading the delayed/debounced status
int buttonState; // variable to hold the button state
int buttonMode = 0; // Is valve on or off?
void setup() {
pinMode(feedValve, OUTPUT); // Set the Feed Valve pin as output
pinMode(returnValve, OUTPUT); // Set the Return Valve pin as output
pinMode(heater, OUTPUT); // Set the Heater Valve pin as output
//pinMode(loopValves, OUTPUT); // Set the Loop Valves pin as output
//pinMode(pump, OUTPUT): // Set Pump pin as output
pinMode(button, INPUT); // Set the switch pin as input
Serial.begin(9600); // Set up serial communication at 9600bps
buttonState = digitalRead(button); // read the initial state
}
double Thermister(int RawADC) {
double Temp;

Temp = 1 / (0.001129148 + (0.000234125 * Temp) + (0.0000000876741 * Temp * Temp * Temp));
