Answer 1

1) The Arduino uses what to assign analog values?

To assign analog values to Arduino, we use analogWrite() function which uses a PWM wave.

2) Which Of the following is NOT an example Of a standard Arduino library?

a) Servo - for controlling servo motors library

b) TFT - for drawing text , images, and shapes on the Arduino TFT screen library

c) LiquidCrystal - for controlling liquid crystal displays (LCDs) library

d) Thermo - No library exists

So, Answer is d

3) The Arduino language uses set of C/C++ functions.

Answer : c

4) How many channels of A/D conversion does the Arduino Uno have?

The Arduino board contains a 6 channel, 10-bit analog to digital converter. So, input voltages between 0 and 5 volts into integer values between 0 and 1023.

Answer : 6 channels

5) The Arduino correlates temperature readings with what value?

It correlates temperature readings in Celsius with voltage output levels.

Answer: c
