 ===== Example =====
+This example uses the MPINO-16A8R8T A0 value as the PID process value. When input D22 changes from LOW to HIGH, it resets the PID state once. It shows the result only in Serial Monitor. Check the A0 setting and D22 wiring against the product specifications.
 <code cpp>
 const uint8_t PID_ID = 0;
-const float SETPOINT_C = 45.0F;
 void setup() {
   Serial.begin(115200);
-  if (!IpidSet(PID_ID, 2.0F, 0.4F, 0.1F, 100, 0.0F, 100.0F)) return;  // Set PID coefficients, calculation interval and output range.
+  IpidSet(PID_ID, 2.0F, 0.4F, 0.1F, 100, 0.0F, 1023.0F);  // Set PID gains, sample interval, and output range.
-  IpidItermLimit(PID_ID, -20.0F, 20.0F);  // Limit the minimum and maximum of the PID integral term.
-  IpidReverse(PID_ID, false);  // Select direct or reverse PID action.
 }
 void loop() {
-  const float temperature = ntcReadf(0);  // Return the NTC 3950 10kΩ sensor temperature as a floating-point value in °C.
+  static bool wasHigh = false;
-  if (IdigitalRead(0, 5)) IpidReset(PID_ID);  // Read the input repeatedly and update only if all samples match. If HIGH and LOW are mixed, retain the previous stable state. / Reset the PID integral value and internal state.
+  const bool isHigh = digitalRead(22) == HIGH;
-  const float demand = IpidRun(PID_ID, temperature, SETPOINT_C);  // Calculate the PID output from the current value and setpoint.
+  if (isHigh && !wasHigh) IpidReset(PID_ID);  // Reset the PID state on the D22 rising edge.
-  const float lastDemand = IpidOutput(PID_ID);  // Return the last calculated PID output value.
+  wasHigh = isHigh;
-  IanalogWritef(0, 0.0F, 100.0F, lastDemand);  // Map the user's floating-point value to the analog output range and output it.
+  const float currentValue = analogRead(A0);  // Read the raw ADC value from A0.
-  delay(20);
+  const float result = IpidRun(PID_ID, currentValue, 512.0F);  // Calculate PID output from the A0 raw value and setpoint 512.
+  Serial.println(result);
+  delay(100);
