Supplementary Material and Support
During your adventures with your Arduino, you'll inevitably have questions and perhaps run into problems. One of the best aspects of using the Arduino is the excellent support community that you can find on the web. This extremely active base of Arduino users will readily help you along your journey. I maintain a list of updated resources for getting help with Arduino, electrical engineering, and embedded software on the Exploring Arduino Resources page:
exploringarduino.com/resources
I used to try to answer people's individual Arduino questions directly, but that's unfortunately no longer possible due to the sheer volume of questions that I receive through my website, Twitter, Facebook, YouTube, and other channels. I highly encourage you to seek help through the forums linked from the Resources page listed here. I can almost guarantee that their response times will be faster than mine.
