Hi all. I am currently working on a 4 motor mindstorm tank. The build went near perfect, but when it comes to programming, I’m not that good. I used the two large motors that came with my ev3 kit along with 2 of the original NXT motors. The older ones work fine with the newer software so that’s not the problem. I’m having trouble getting all the motors to run simultaneously to make it for forward or backwards. I’ll post the current program that I tried to use once I power up my laptop. Below are photos of the wiring and the general layout. I’d appreciate any and all help.
