The PWM pins in an Arduino board are found in the analog pins
True
False
analogWrite(pin , val) set the PWM duty cycle as a
Scale of 0 – 255
Scale of 0 – 1023
Scale of 0 – 5
Scale Only 3.3 V
What is the correct instruction that matches correctly with the comment:
__________________; //Makes the output of pin 3 with duty cycle of 127 ?
pinMode(3, 127)
digitalWrite(3, 127)
analogWrite(3, 127)
digitalRead(3)
What is the correct instruction that matches correctly with the comment:
int value =_________________; //reads the value of A0 in PORTC ?
pinMode(A0,OUTPUT)
digitalWrite(A0,HIGH)
analogRead(A0)
digitalRead(A0)
R1: int Led1=4;
R2: void setup(){
R3: digitalWrite (LED1, High);
R4: }
