Good afternoon, I need to make a program that regulates the speed of a motor
(0-10 V) depending on the number of digital inputs activated (I1, I2, I3 and I4).
If there is only one input activated, the motor speed must be 50% (5V), if there
are two inputs activated it must be 66% (6.6V), if there are 3 inputs activated it
must be 80% (8V). ) and if the 4 inputs are activated, the speed must be 100% (10 V).

I can't do it. Could you help me? Thank you so much.
