 ### Soldering the electronics
 1. Solder on two rows of 8 male pin headers to the D1 mini

 3. Solder on two rows of 8 female pin headers to the motor shield as well as a single row of bent pins. 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. Here is a schematic:

+*Note: I added a new connector instead of using the one already on the battery shield because the plug of my battery wouldn't fit in the on on the shield*
+
+|First, solder two wires to the + and - pins of the battery shield and isolate them with heat shrink:   |
+|--------------|---------------|
+|Cut two small pieces of wire (about 4 cm), remove the isolation on both ends and cover them with a bit of solder            |   ![Battery Shield Wires](https://imaginaerraum.de/git/Telos4/RoboRally/raw/branch/master/docs/images/motor_batter_stack_2.jpeg)|
