I need to control 8 motors from Arduino.
speed control only with a single pwm output
I use a single channel at time
I have 74hc4051 analog/digital mux/demux ic
if I set mosfet drive circuit with gate pull down (40kOhm) and gate resistor 100Ohm on all output channels of 74hc4051
I need to know weather there is a possibility to generate floating noise on unused channels?
according to theory since I am using mosfet gate pull down on each output of mux channels floating noise will be pulled to ground is this correct?
analog mux output connects to mosfet gate
