Boost converter Dengan PWM Arduino Nano

Circuit:

Code:

int potentiometer = A0; //The input from the potentiometer is A0 int feedback = A1; //The feedback input is A1 int PWM = 3; //Digital pin D3 por PWM signal int pwm = 0; //Initial value of PWM width void setup() { pinMode(potentiometer, INPUT); pinMode(feedback, INPUT); pinMode(PWM, OUTPUT); TCCR2B = TCCR2B & B11111000 | B00000001; // pin 3 and 11 PWM frequency of 31372.55 Hz } void loop() { float voltage = analogRead(potentiometer); //We read the value of the potentiometer, which is the desired value float output = analogRead(feedback); //We read the feedback, which is the real value //If the desired value is HIGHER than the real value, we increase PWM width if (voltage > output) { pwm = pwm+1; pwm = constrain(pwm, 1, 254); } //If the desired value is LOWER than the real value, we decreaase PWM width if (voltage < output) { pwm = pwm-1; pwm = constrain(pwm, 1, 254); } analogWrite(PWM,pwm); //Finally, we create the PWM signal }
