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 ...

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, ...

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 ...

Here’s an interesting article about reading data from shift registers using less than three pins. 74HC165 shift registers are a popular choice for adding inputs to a microcontroller. They have a ...

The Arduino Esplora is a ready-to-use, easy-to-hold controller that lets you explore the infinite possibilities you have in the world of Arduino, without having to deal with breadboards or soldering.

The long-awaited Arduino Due just hit the market, replacing the 8-bit, 16MHz brain of the popular Uno microcontroller prototyping platform with a 32-bit, 84MHz processor, while augmenting inputs and ...

In recent years, integrated platforms equipped with microcontrollers (with Arduino probably being the best-known brand) have been gaining popularity.

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...
