How can I use more than three motors with one NXT brick?
I want to make a tank out but it needs 4 movement bricks but I only have one NXT. Here are the parts:
- It can move and that takes up two motion bricks so it can turn, move forwards and backwards.
- It uses one movement brick for the gun.
- it uses one movement brick because it will have a hatch that can open so that it can collect the balls that it has already shot so I don't need to get them manually.
