Grove - Thumb Joystick
Sold outGrove - Thumb Joystick is a Grove compatible module which is very similar to the ‘analog’ joystick on PlayStation 2 controllers.
Overview
The X and Y axes are two ~10k potentiometers which control 2D movement by generating analog signals. The joystick also has a push button that could be used for special applications. When the module is in working mode, it will output two analog values, representing two directions. Compared to a normal joystick, its output values are restricted to a smaller range (i.e. 200~800), only when being pressed that the X value will be set to 1023 and the MCU can detect the action of pressing.
Features:
- Grove Interface
- 5V/3.3V Compatible
- Analog Output

Easily monitorize your garden's environment with simple components.
Greenhouses are excellent ways to grow plants due to their compact nature and the fact that they can absorb and store the sun’s light as heat to keep their internal temperature higher than outside. But when it comes to adding ventilation for cooling things down, decreasing the humidity, or simply to avoid rain, most non-commercial ones still rely on someone to manually open or close the windows. This need for automation is what drove Michael Bernhard to create his own greenhouse climate regulation system. This project relies on a Nano Every to read the ambient temperature/humidity as well as control up to six motorized windows via three L298N dual H-bridge drivers. The Nano receives commands and other data over WiFi from an accompanying ESP8266 board for wireless remote control with a mobile phone. Each of these components and their connectors were added to a custom PCB and placed within a simple wooden enclosure to keep moisture out. An LCD at the top shows pertinent information such as the time, temperature, and humidity. The aforementioned WiFi control scheme not only allows for remote control of the windows, but also for the visualization of historical sensors data on a graph. Safety information, including errors and stored EEPROM data, can be viewed on the web application, too. To see more about this project, you can read Bernhard's write-up here on Hackster.io.
