Summary

This has been a very busy chapter where you have been making circuits, programming them, and learning about new sensors and servos. We started by using the Circuit Playground board to explore one of the many sensors: an accelerometer. We used this onboard sensor with NeoPixels to track movement. This was a great way to see firsthand the fun we can have with NeoPixels! Using the sensors on the Circuit Playground board is a great way to add interactivity to future projects. It demonstrates that we can use the sensors onboard to test code and circuits quickly.

Then, we jumped straight into understanding flex sensors. We looked at using an off-the-shelf component, but also how we can build our own. Being able to build sensors opens a whole new world for your wearables. You can start to plan your circuits and make the sensor fit easily with the body part you desire. We also used a multimeter to help us take readings from the sensor to make sure it was working.

Lastly, we...
