Initially, the state of an input pin will be very unstable because the voltage that flows into the pin is very inconsistent, this is called a
(a)
There is two techniques we can use to prevent floating inputs, they are
Pull-up resistor
Push-up resistor
Pull-down resistor
Push-Down resistor
Which one below is correct?
which one below is the correct way to connect a pull-down resistor?
Which one below is true?
Digital only can be 0 or 1
Digital can have as many possible values as possible as long as all the values are continuous
Analog only can be 0 or 1
Analog values have infinite possible values as all their values are continuous, for example temperature
Which of the following is/are true?
analogRead will give us a value between 0-1023
analogRead will give us a value between 0-255
analogWrite can write a value between 0-1023
analogWrite can write a value between 0-255
if I supply 1.7V to A2, and by using analogRead(A2)
I will get around 348, is this true?
1.7/5 = 0.34
0.34 * 1024 = 347.82
True
False
