Now that you know how the Rabbit RCM5450W module works and how to interface relays and an LCD, it’s time to set up your sprinkler system.
This self-contained, battery-powered unit measures both DC current and voltage. It accepts four of the most common wall wart plugs and also has four identical output plugs — ready to hook to your project.
It’s here! We’re graduating from our 16-bit Experimenter so we can experience a whole new level of applications with the 32-bit version.
With an understanding of IR codes, a wide range of devices can be built that offer new remote control capabilities.
