2 Button to 1 PWM output

Projects General Guidance

1. I recommend you to follow the diagram of Fig-1; where,Button is connected at DPin-2 and not DPin-1 as it is engaged with Serial Monitor/PC/IDE.

2. Upload the following sktch and report the result.

#define Switch 3
#define Button 2
#define PWM 11

void setup() 
{
  Serial.begin(9600);
  pinMode(Switch, INPUT);
  pinMode(Button, INPUT);
}

void loop() 
{
  if(digitalRead(Switch) == LOW) //Switch is opened
  {
    analogWrite(PWM, 255); //100% duty cycle ~= 5V
  }
  
  if(digitalRead(Switch) == HIGH)  //Swicth is closed
  {
    analogWrite(PWM, 128);  //50% dut cycle ~=2/5V
  }
  
  if(digitalRead(Button) == HIGH) //Button is pushed
  {
    analogWrite(PWM, 0);   //0% duty cycle ~=0V
  }
}
