If you’re into SBCs, you have probably pushed your Raspberry Pi to the limit with countless DIY projects. A Raspberry Pi is a powerful microprocessor that can replace entire appliances and become the core of your smart home. An Arduino microcontroller, on the other hand, might not be as powerful, but it’s perfectly suited to simpler yet equally helpful projects. An inexpensive Arduino board can actually solve tons of real home problems, from bolstering your home security and watering your plants to feeding your pets. You just need to be comfortable with a bit of coding and breadboarding, and the world is your oyster.
