Every once in a while a project comes along with that magical power to consume your time and attention for many months. When you finally complete it, you feel sorry that you don’t have to do anything ...

We’ve seen NES, SNES, Sega, and just about every weird controller Atari put out connected to microcontrollers, but connecting the N64 controller to a project has remained one of those seldom-seen, ...

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 ...

Meet the Raspberry Pi Pico 2 W, a tiny board designed around a microcontroller that lets you build hardware projects at scale. Raspberry Pi is once again using the RP2350, its own well-documented ...

Microcontroller port pins can typically be driven either high or low, or else be put into an "input" or high-impedance state. This circuit uses the three states to drive two separate LEDs with one ...

What are Microprocessors and Microcontrollers? Microprocessors and microcontrollers are essential components of an embedded system. These are single-chip processors that accelerate the computing ...
