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 ...

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 ...

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 ...

Inputting multiple bits of information using a single entry pin of a microcontroller without the complexity of UARTs can prove useful. Such a scheme could allow scanning of a keyboard, mode switches, ...

An automotive body control module (BCM) is an electronic control unit (ECU) that manages a wide range of vehicle comfort, convenience, and lighting functions, including the central locking system, ...

I recently purchased an RGB vandal switch for my PC. I didn't pay too much attention and assumed each color had its own positive and negative lead and you could just plug Red into the power header, ...
