Yfs201 Proteus Library ✦ (Secure)

#include <LiquidCrystal.h> LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

Modify code:

volatile int pulseCount = 0; float flowRate = 0.0; float totalLiters = 0.0; unsigned long oldTime = 0; yfs201 proteus library

// Frequency = pulses per second float freq = pulseCount; flowRate = freq / 7.5; // L/min totalLiters += flowRate / 60.0; // liters added this second

void setup() pinMode(2, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(2), pulseCounter, RISING); lcd.begin(16, 2); lcd.print("Flow Meter Ready"); delay(2000); lcd.clear(); oldTime = millis(); #include &lt;LiquidCrystal

| Benefit | Explanation | |---------|-------------| | | No need to buy physical sensors for initial testing | | Rapid prototyping | Test code changes in seconds | | Debugging | View pulse trains, count interrupts virtually | | Education | Safe environment for students learning flow sensors | | Hardware independence | Simulate even when sensor is out of stock |

void pulseCounter() pulseCount++;

| Issue | Impact | |-------|--------| | No fluid viscosity model | Cannot simulate real-world turbine lag | | Perfect square wave | Real sensor has jitter, voltage droop | | No temperature compensation | Real sensor output drifts with temp | | Limited community libraries | Some versions are buggy or untested | | No pressure drop model | Simulation ignores backpressure |
