What’s a Microcontroller?
by Parallax.com
What’s a Microcontroller? is a first-step BASIC Stamp 2 tutorial, introducing the essentials electronics and programming side by side. You will write PBASIC programs and build both simple and advanced breadboard circuits with LEDs, pushbuttons, potentiometers, light sensor, a servo, and much more! The text is designed to accommodate a wide range of ages and skill levels and is a great resource for STEM programs. This ebook is for anyone interested in getting started with microcontrollers and electronics.
