Digital inputs

Ruddock984

Hi all,

I am using a load cell with Arduino, when a load is reached an output is turned on. I am using a relay to switch 5V to 12V and want this to turn an input on in the ur10. The 12V power supply for relay is rated current output of 2250mA. The max ON current on the ur10 is 10mA so do I need to reduce current to 10mA or will the ur pull whatever it needs from the power supply

The digital input on the UR controller is self limiting, you don't have to reduce current. Keep in mind that the CB3 minimum ON threshold is 11V.

in terms of programming then. if i want the robot to stop moving in a certain direction until the input is turned on. what way would i go about doing this

This should give you some ideas

This doesn't really answer it. I need the robot do keep moving until the input in turned on and not at a way-point. Essentially I have a robot and lever mechanism. the arm is at 1 end of lever mech and the load cell with Arduino at the other. The robot will move the lever and when a force defined in the arduino is reached, the output is turned on. the robot needs to keep moving and stop when the output nis turned on. 

This may be a question for the programming section of the forum
