Automatically monitor and irrigate your raised garden bed with the Arduino Cloud
Initially, Murphy had researched constructing a pump that could take water from a pair of rain storing barrels and deliver it to the garden bed. However, this would have been costly to build and maintain, so he instead went with a gravity-fed setup. In this configuration, gravity would move water down-slope to a solenoid valve attached to the Arduino IoT Explorer Kit’s 24V relay pin. Once wired together, he added a soil moisture sensor for measuring the water content of the soil, along with a 12V battery pack and solar charge controller for off-grid power.

A RISC-V Supercluster For Very Low Cost
As ARM continues to make inroads in the personal computing space thanks to its more modern and streamlined instruction set architecture (ISA) and its reduced power demands especially compared to x86 machines, the main reason it continues to become more widespread is how easy it is to get a license to make chips using this ISA. It’s still not a fully open source instruction set, though, so if you want something even more easily accessible than ARM you’ll need to find something like these chips running the fully open-source RISC-V ISA and possibly put them to work in a custom supercluster.
