MyPlantPet

This repository provides the code to build and run your own MyPlantPet.

Requirements

Software

For App:

• Expo version 42+ (Requires ExpoKit with run:android)
• Android SDK
• ADB

For Device:

• PlatformIO with support for ESP32
• OpenScad for generating STL for planter *

* - coming soon

Hardware

For App:

• Android device with BLE

For Device:

• TTGO T-Display (ESP32 device with color screen and free touch pins)
• 3D printer to bring STLs to life
• Soldering iron
• Wires
• Hot glue gun
• Female USB-C port (optional)

How to use

App

Configure your Android SDK directory, either as an environment variable, or put the following in /app/MyPlantPet/android/local.properties:

sdk.dir=/home/path/to/Android/Sdk

After that connect a physical Android developer device to your machine and run:

adb devices

This should start the adb daemon, and list your device. If it doesn't, then please fix that before proceeding. Once that works, you can just navigate to the app directory and start the app as follows:

cd app/MyPlantPet
expo run:android

This makes Expo build the APK for your project and install it on your Android device. During this compilation, there might be a failure in node_modules/@jaidis/react-native-ibeacon-siimulator/android/src/main/java/com/ibeacon/simulator/BeaconBroadcast.java about import android.support.annotation.Nullable. Modify the file as follows:

import androidx.annotation.NonNull;
// import android.support.annotation.Nullable;

This should fix it and you should be able to run expo run:android again.

Device

Load up the device/MyPlantPet directory in your PlatformIO IDE of choice (I use VSCode). Once PlatformIO loads up and makes dependencies available, you can upload the project to the TTGO T-Display device and it should just work.

Planter

Print the STL (not published yet, in the process of building a custom device design), solder wires to pin 12, 13, 5V, GND as follows:

ESP32	Planter
12	Plant
13	Plant
5V	USB-C 5V
GND	USB-C GND

Make sure that the wires for the connections have been routed correctly through the planter and the USB-C plug is placed in the correct position. Once this is done, hotglue all the holes where water and soil might interact with the electronics to keep things safe. Wires are OK since they have plastic insulation, everything else would need to be coated.

That's it, now when the Planter is powered by the USB-C, it should turn on and display a code for you to use with your app.
