Question

334) An Arduino analog input voltage is 4.320 volts. The Arduino PWM output

pin drives a low-pass filter, which converts the PWM signal back to an

average-DC voltage. Arduino specifications include: I/O voltage ranges

of 0 to 5VDC; 10-bit A/D; and 8-bit D/A PWM output. The analog voltage DC

input results in an analog output DC volage at the low-pass filter.

Determine (Vout - Vin). Arduino functions include: analogRead(), map(),

and analogWrite(). The analogRead() and map() use integer I/O.
