I have one of speed controller and I am not impressed with it speed control any ideas how to improve it preforms
This is not the seller that I bought this item from
https://www.ebay.com/itm/1PC-Engravi....c100290.m3507
I have tried to a 500 ohm resistor between the two input and 1k ohm resistor on the positive input wire its response is a little bit better but not what I expect it to be of the PWM because the one seller has the input 3 to 12 volts another one seller has the input as 0 to 5 but nether one seems to work right
But the resistor that is on the optic sensor is 470 so I assuming that it is really 0 to 5 volts but the Arduino Nano PWM output is 0 to 12 volts at M3 S1200 this value is at full speed
