Make sure they are soldered on the right way around. 4. In addition solder a jumper to the motor shield to connect the RTS and 3V pin. This will become important later on. Also solder the I2C bridge. - - - Note: -3. Connect the + pin of the connector from the battery shield to the + pin of the motor shield. -For this cut some small piece of wire and remove the isolation on both ends. then twist the ends and put some solder on both ends. Cut a piece of isolation and wrap it around the wire. Make sure you do this before soldering on the second end of the wire. -After this is done, repeat the same with the - connection. Please make sure that you do not reverse the polarity! +3. In the next step we connect the battery connector pins of the battery shield to the + and - pins of the motor shield. In addition we will add a connector to the motor shield where we can plug in the battery.
