ScrewShield Holds Wires in Place

Loose wires are probably the most annoying thing while building a prototype. Arduino’s header pins can’t hold the jumper wires securely. Especially when your robot is moving, wires pop out constantly. Luckily the ScrewShield pretty much solves this problem.

ScrewShield adds “wings” with terminal blocks to both sides of Arduino. Terminal blocks have screws so you can attach one or more wires firmly to any pin.

You have to do some soldering when building the ScrewShield, but it will pay off later on. As an added bonus, you’ll get nice and relatively easy soldering practice. Of course you can make the robot we are building here without the ScrewShield, but we strongly suggest that you use it. The Appendix A explains how to build the ScrewShield.

This completes your robot chassis! You now have a moving robot platform. In the next chapter, you’ll be coding the mind-controlled robot part by part. What other projects could you do with your new robot chassis?
