If you know C, you will love Arduino. It&#x27;s very easy to &quot;to speak to a web API&quot;. They are usually low power 8-bit CPUs with 16 MHz, exactly right for small projects like blinking some lights that should run on battery for years.<p>JavaScript&#x2F;Python&#x2F;etc on RaspherryPi or this new Mozilla thingy are interesting too, though will drain your battery faster. You need an OS on a 32bit CPU. If it&#x27;s connected to the web you should also update the software stack.
