I am trying to make the robot in the start here section. The motors work when I hold the wires to batteries but when I try to attach them to the board they don't work. I have followed the instructions carefully and soldered the wires to the pins (as I don't have connecters). I have tried several times and am still stuck. This robot is for a school project and has to be ready in two days. I really don't know what to do can anyone help?
