In this episode, I will make the circuit board and a stand for the robot and upload the Arduino code.
We are going to use a pair of this servo board. To use the servo board together, we need to change the address by soldering one point. Put all the circuits together and connect wires like this picture.
If you already followed previous episodes, this step will be easy for you. We don’t need to use cables to connect the pair of servo board. I just soldered them together.
By the way, I was trying to solder with lead-free thread. It is somehow more difficult than a typical lead.
