Arduino library for the AD9833 function (waveform) generator (12.5 MHz) The library supports both hardware SPI and software SPI. The AD9833 is a signal generator that has two channels for frequency ...

The CatGenie is an amazing device to watch in action, basically a self-cleaning litter box for cats that even does away with the need to replace the litter. It’s comparable to what the indoor flush ...

If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

In this creative project, we dive into classic gaming with this circuit that brings the iconic Tetris game to the Arduino platform! This project is also available at Max Imagination's Workshop.

This direct digital synthesis IC can function as an arbitrary waveform generator by bypassing the SIN table ROM, holding the phase accumulator at zero, and using the phase register as the ...

Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this ...

Some of us have this innate desire to make things on our own and relish the challenge of learning something new. If that sounds like you, then you’ll probably enjoy leveling up your smart home ...

Pondering the lack of a numerically-controlled oscillator (NCO) peripheral on AVR-based Arduinos (compared to PICs), I started to look into doing it in software. But it turns out that the necessary ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as ...
