The programm which turns on pneumatic valves through 8 Channel servo controller on EV3 (the brick with a "horse") worked perfectly just 3 month ago, and when I tried to run it today it just does not recognize 8 Channel Servo Controller and does not do any moves. I checked the batteries and they are fine, all connections are correct and they are as they were 3 months ago. The Port View always had problems recognizing Mindsensors but the program worked regardless. Now, the EV3 port does not recognizes 8 Channel Servo Controller, and there is nothing I can do about it. However, it seems that without recognizing the controller the pneumatic valves will not work. Any ideas?
