ARRL’s “Best of Arduino Projects for Ham Radio” features updates to the most popular projects from the three previous Arduino books written by author Glen Popiel, KW5GP, and published by ARRL. New components include LED displays, contemporary Arduino microcontrollers, more efficient software sketches, shields, and many other components. If you’ve built these projects before, you’ll find innovative new ways of overcoming their challenges, and if you’ve never built an Arduino project, you’ll find intuitive, step-by-step guidance on how to put together a workbench, test, and troubleshoot, and — of course — expert guidance on constructing each project. You won’t just learn from Glen, but from the whole open-source community. Start a project today!
