 ===== Example =====
+This example reads the raw A0 analog value (0–1023) on MPINO-16A8R8T for the PID calculation. It shows the result only in Serial Monitor and does not drive an output. Check the A0 voltage/current setting for the connected sensor.
 <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.
+  const float currentValue = analogRead(A0);  // Read the raw ADC value from A0.
-  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 float result = IpidRun(PID_ID, currentValue, 512.0F);  // Calculate PID output from the A0 raw value and setpoint 512.
-  const float demand = IpidRun(PID_ID, temperature, SETPOINT_C);  // Calculate the PID output from the current value and setpoint.
+  const float lastResult = IpidOutput(PID_ID);  // Read the most recently calculated PID output.
-  const float lastDemand = IpidOutput(PID_ID);  // Return the last calculated PID output value.
+  Serial.println(lastResult);
-  IanalogWritef(0, 0.0F, 100.0F, lastDemand);  // Map the user's floating-point value to the analog output range and output it.
