# Circuit Playground Slouch Detector ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/038/022/medium800/circuit_playground_CP_angles_banner.jpg?1481901576) In this guide we will go through the steps to turn your Circuit Playground into a slouch detector. Using one of several pinning options along with various battery supply options, you can then wear your Slouch Detector while sitting at a desk. It will provide a warning if you, well, get a little slouchy - hopefully with reminders, you can keep your good posture and maintain a healthy back! # Required Parts This project uses the sensors already included on the Circuit Playground, either a [Classic](https://www.adafruit.com/products/3000) or an [Express](https://www.adafruit.com/products/3333). The only additional items needed are batteries for power and a holder for the batteries. - Circuit Playground - [Classic](https://www.adafruit.com/products/3000) - [Express](https://www.adafruit.com/products/3333) - [3 x AAA Battery Holder](https://www.adafruit.com/products/727) - 3 x AAA Batteries (NiMH work great!) ![circuit_playground_items.jpg](https://cdn-learn.adafruit.com/assets/assets/000/038/001/medium640/circuit_playground_items.jpg?1481831454) # Optional Parts These items help make this project more wearable. There are a couple ways to pin the Circuit Playground in the right location. Additionally, there are a few smaller sized battery options to make it more pocketable. A battery extension cable allows for placing the battery in a different pocket. - [Silver Pin Back](https://www.adafruit.com/products/2838) - [Magnetic Pin Back](https://www.adafruit.com/products/1170) - [JST Extension Cable](https://www.adafruit.com/products/1131) - [LiPo Battery](https://www.adafruit.com/products/1578) - [Coin Cell Battery Holder](https://www.adafruit.com/products/783) - [Coin Cell Batteries](https://www.adafruit.com/products/654) ![circuit_playground_items2.jpg](https://cdn-learn.adafruit.com/assets/assets/000/038/003/medium640/circuit_playground_items2.jpg?1481831764) # Before Starting If you are new to the Circuit Playground, you may want to first read these overview guides. ## Circuit Playground Classic - [Overview](../../../introducing-circuit-playground) - [Lesson #0](../../../circuit-playground-lesson-number-0) ## Circuit Playground Express - [Overview](../../../adafruit-circuit-playground-express/) - [Next Page](https://learn.adafruit.com/circuit-playground-slouch-detector/hello-slouch.md) ## Featured Products ### Circuit Playground Express [Circuit Playground Express](https://www.adafruit.com/product/3333) **Circuit Playground Express** is the next step towards a perfect introduction to electronics and programming.
