step 11the antenna!

You are going to give your little robot some way to feel the world.

Take the small paperclip and bend them to form some antenna.

Glue them on the metal plate pf the SPDT switchs.

I don't recommend soldering them because you need some aggressive acid-based flux or silver solder. If you don't have any experience in soldering, you will melt them.

I have already solder some using silver solder.
