# Cheekmate - a Wireless Haptic Communication System ## Overview ![Plastic capsule containing electronics](https://cdn-learn.adafruit.com/assets/assets/000/115/587/medium800/gaming_cheekmate-banner.jpg?1664927537) Social media is abuzz lately over the prospect of **cheating in tournament strategy games**. Is it happening? How is that possible with officials watching? Could there be a hidden receiver somewhere? What can be done to rectify this? These are probing questions! We’ll get to the bottom of this by making a simple one-way **hidden communicator** using **Adafruit parts** and the **Adafruit IO service**. _Not for actual cheating_ of course, that would be asinine…in brief, a stain on the sport…but to record for posterity whether this sort of backdoor intrusion is even plausible or just an internet myth. Warning: ## Parts The project requires a **soldering iron** and related paraphernalia, and the following Adafruit items: ### Adafruit QT Py ESP32-S2 WiFi Dev Board with STEMMA QT [Adafruit QT Py ESP32-S2 WiFi Dev Board with STEMMA QT](https://www.adafruit.com/product/5325) What has your favorite Espressif WiFi microcontroller, comes with [our favorite connector - the STEMMA QT](http://adafruit.com/stemma), a chainable I2C port, and has lots of Flash and RAM memory for your next IoT project?
