It's been a long time since I didnt dive into my hobby again. After having built two awesome remotely controlable robots to play with my cats when I'm away, I am now trying to retrofeed a Neato XV21 vacuum into a floor scrubbing robot, using an EZB to activate a pump that will inject the cleaning solution when the wheels are running.
I wish to deactivate the fan that generates suction in order to save battery but the program won't allow it since it sends a message saying that the fan is not running.
The fan has 4 wires : one Red and one Black, obviously for power, and one Blue and one Yellow.
I assumed the Yellow and the Blue ones are signal cables but I have no idea how to make the robot think that the fan is running. I'm considering sending a 5V low amp signal to the blue wire just in case.
If someone has any idea on how to deal with this, that would be great.
Thanks a lot,
