# Clock That Is Wrong

A 7-Segment Clock that displays the wrong time when it detects someone looking at it.

## Hardware

You will need:

- [Adafruit QT Py ESP32-S2 dev board](https://www.adafruit.com/product/5325) (or any ESP board with a STEMMA QT connector)

- [Person Sensor](https://usefulsensors.com/person-sensor/)

- [Adafruit 7-Segment Display with I2C backpack](https://www.adafruit.com/product/878) (any color)

- [2 STEMMA QT/ Qwiic Cables](https://www.adafruit.com/product/4399) (one should be > 50mm)

- (optional) Filament to 3D print the [case](case_stand.stl).

### Wiring 

1. Connect the Person Sensor to the 7-Segment backpack using a STEMMA QT cable.

2. Connect the ESP-32 dev board to the other STEMMA QT port.

## Software

1. Get CircuitPython [running on your dev board](https://learn.adafruit.com/adafruit-qt-py-esp32-s2/circuitpython).

2. Install the following libraries:

   1. `adafruit_ht16k33` (from the adafruit library bundle)

   2. `adafruit_requests.mpy` (from the adafruit library bundle)

   3. `adafruit_ticks.mpy` (from the adafruit library bundle)

   4. [`person_sensor`](https://github.com/dupontgu/person-sensor-circuitpython)

3. Load this repo's [`code.py`](code.py) file onto the dev board.

4. Edit the timezone, wifi ssid, and password at the top of that file to fit your needs.

5. That should be it!
