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 ...

There are several ways to readmultiple switch inputs using areduced number of microcontroller-unit(MCU) pins. For example, you can usean analog MCU pin to read multipleswitches by assigning a unique ...

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 ...

Designed by Guimpt in Spain, the IoT HDMI Switch is an ESP32-C3-based open-source HDMI switch that integrates with Home Assistant and ESPHome to automate ...
