If you can put a relay output on it then you could wire one of the UR inputs to that relay and then by using the relay you can then signal the UR input

If you need more then 0 or 1 to send to the robot you can use the arduino + ethernet shield and use modbus library ,I used it and is working .

So I decided to use a raspberry pi instead, I was having trouble with connecting the Arduino uno to wifi. I am going to use the blynk app to have one of the GPIO pins give an output signal that will then activate the relay and so give a digital input to the UR3. Does this sound right?
Sounds good. Just be sure to pull all 24v signals from the robot's controller to avoid damaging circuitry, Also, to be fully autonomous, you'll need to enable remote control in polyscope, and might need more than one input to the robot to start, depending on the robots program.
Hi,
I suggest you to have a look on this SDK : https://underautomation.com
It allows you to remote control the robot (Send UR Script, power on, release brake, ...) but also read data (cartesian and joint position, I/O, ...).
It has a linux ARM example that can run on a Raspberry PI. But you can customize this example for your needs.
