The circuit in this Design Idea provides a way to convey mixed analog and digital inputs into a microcontroller using one input pin. The output of the circuit connects to a micro-controller's ...

Debouncing button or switch inputs on microcontrollers can be a challenging problem for those first starting to program these devices. Part of the reason for this difficulty is that real-world buttons ...

Using the analog converter input function of a compact microcontroller’s input pins to read ternary logic encoding allows two pins to sense as many as nine configuration states. When designing with ...

We used to need SBCs for these projects; modern microcontrollers handle them more easily and inexpensively while being easier ...

Rotary encoders are pretty interesting pieces of technology. They’re a solid way to accurately measure rotation including the direction. [David] recently wrote some software to handle these input ...
