Hello
I have purchased a robot arm from amazon that is servo driven. looking at other projects on project hub I have noticed that many people use pots to control the robot thru the analog pins on the arduino by changing the voltage. I am wondering if I could take a Analog Output card of a Allen Bradley PLC and control the voltage to the analog pins of the arduino and receive the same results? Has anyone done this before? Is there anything i should pay attention to. I am very new to arduinos
As long as the PLC output is maximum 0 -5 volt. There should be some spec's on the Robotic arm on interfacing. You should at the Servo library and examples and also do a study on servo motors if unfamiliar with them and how to drive them.
