An evaluation board — also known as a development board or evaluation kit—is a pre-assembled circuit board designed to help developers, engineers, and hobbyists experiment with a specific microcontroller or system-on-chip. These boards provide everything needed to start prototyping, learning, or debugging, without needing to build a circuit from scratch. For those working with AVR … Read more
In embedded systems, a push button or mechanical switch may seem like the simplest of input devices. But under the hood, there’s a common challenge known as switch bounce—rapid, unintended signal changes caused by the mechanical nature of switches. Without proper switch debounce, these false triggers can confuse digital systems and lead to erratic behavior. … Read more
