Can anyone fix the Arduino uno code?I wanted to write,first measure the input voltage by using voltage sensor.And after that,if its not in the range of 20-22 V,adjust the duty cycle of mosfet in the converter until the voltage becomes in the range 20-22 V.

so the aim is to make output 20-22 V

int analogInput = 10; #define PWM_out 6 float vout = 0.0; float vin= 0.0; float R1 = 30000.0; float R2 = 7500.0; int value = 0; int pwm_value = 0; void setup() { pinMode (analogInput, INPUT); Serial.begin (9600); Serial.println("BASIC DC VOLTMETER"); } void loop() { value = analogRead (analogInput); vout (value + 5.0) / 1024.0; vin = vout / (R2 / (R1+R2)); "); Serial.println(vin, 2); Serial.print("Voltage delay(500); if (vin > 20.0 && vin 20.0 && vin
