Raspberry PI + Moisture Sensor with Python (wiring, code, step-by-step walk-through)

Growing Strawberries with a Raspberry Pi, on autopilot, EP#2 In this episode, I'll start to add the specific hardware that my automated gardener needs. And the first piece will be the moisture sensor. 00:00 Intro 01:15 What’s the best moisture sensor? 02:13 Wiring 03:53 Rasperry PI via command line 05:17 Installing prerequisites (apt-get update, etc.) 06:45 Installing text editors for coding 08:47 Installing moisture sensor packages and libraries 14:39 Testing the moisture sensor code! 15:36 ERROR!!! (No I2C device at address: 0x26) 16:40 It works! 18:14 Let’s try to understand and modify the code! 22:28 Prototyping the water pump logic with a simple if statement 24:37 Conclusion THE TOOLS I USE IN THIS VIDEO: Raspberry Pi 4 (Model B) Adafruit STEMMA Soil Sensor - I2C Capacitive Moisture Sensor: https://www.adafruit.com/product/4026 LINKS AND CODE BASE FOR EACH STEP: STEP #1 - wiring: https://learn.adafruit.com/adafruit-s... STEP #2: Prerequisites: https://learn.adafruit.com/circuitpyt... STEP #3: Installing mcedit and Sublime Text: sudo apt-get update mc OR https://data36.com/sublime-text-data-... STEP #4 - Python Installation of seesaw Library: https://learn.adafruit.com/adafruit-s... STEP #5 - Enabling I2C, SPI and installing RPI.GPIO + adafruit-blinka: IMPORTANT! After I’ve recorded this video, Adafruit changed their tutorial, so you EITHER follow their new stuff, here: https://learn.adafruit.com/circuitpyt... OR you follow the stuff in the video by running these lines: sudo apt-get install -y python-smbus sudo apt-get install -y i2c-tools sudi raspi-config sudo reboot sudo i2cdetect -y 1 sudi raspi-config sudo reboot ls /dev/i2c* /dev/spi* pip3 install RPI.GPIO pip3 install adafruit-blinka STEP #6 - Testing Blinka: https://learn.adafruit.com/circuitpyt... STEP #7 - Actually installating the seesaw Library: https://learn.adafruit.com/adafruit-s... STEP #8 - Using the moisture sensor code: https://learn.adafruit.com/adafruit-s... STEP #9 - The modified version of the script that I used at the end of the video: https://github.com/tomimester/automat...
