Learn to use soil moisture sensors, both resistive and capacitive.
After calibrating our sensors, we will use them to build two projects. One of them is a soil moisture meter, the other is an automated watering system that uses the Arduino IoT Cloud.
The WiFi Stepper is exactly what its name would imply – a board that lets you control a stepper motor via WiFi. Its full-featured web-based interface gives you complete control of your motor, and it can support steppers of all sizes up to 85 volts at 10 amps!
Today I’ll demonstrate how to use this versatile board. I’ll hook it up, learn how to use it and even run a simple Bash script on a Raspberry Pi to demonstrate how to incorporate it in your programs.
