A Py/mPy auto irrigation system with push notifications to Android, and rainfall prediction with Darksky API for more efficient water usage.
The idea of this tutorial is to provide examples of how to read sensor data with MicroPython devices.
Then how to do some useful stuff with that sensor data, using a RPi running its bigger sibling, Python. You will find examples of code that can be used for measuring distance (Water Level), controlling relays (The Pump), Soil Moisture (Capacitive Soil Moisture), Temp & Humidity (DHT11) and Light level using a photoresistor. The RPi code shows how to send Push notifications, write data to a Google Sheet, request weather forecast data from Darksky and how to use HTTP requests with a web app to monitor and interface with your mPy devices.
Secondly, to build an example code framework which can be quickly and easily modified to use for all future mPy projects. The setup being infinite mPy children contacting a Flask parent, who performs the complex functions the children cannot. This framework includes a standard boot.py for the children (Connect to WiFi, use NTP to set time) and a list of the definitions which need to be added to the parent web app to allow a new device to connect.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
