Arduino is a great microncontroller package for entry-level electronics tinkerers, but once you've got your sea legs, cheaper DIY microcontrollers used to build anything from grow-lights to irrigation systems are what you might reach for next
The Arduino platform is doing something amazing: bringing hardware development to the masses. It's a sweet little system, with a built-in hardware programmer, simplified programming language, and lively user base that offers plenty of sample code and assistance in the online forums. While this fully assembled solution is a good way to get your feet wet, there are a lot of good reasons to just buy an off-the-shelf processor, make your own circuit board and write in a low level language like C. It can be cheaper, quicker and easier to debug. Here, check out some of the projects I've made and how I pay for my hobby, as well as my hardware setup.
