The Arduino UNO, powered by ATmega328P, stands as a microcontroller equipped with 14 digital I/O pins, among which 6 facilitate PWM output. Additionally, it features 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, an ICSP header, and a reset button. This Uno serves as a user-friendly plug-and-play device. To […]

Introduction This guide provides a concise overview of initiating Arduino microprocessor programming through the Arduino Integrated Development Environment (IDE). While these instructions cater specifically to the Arduino Nano board utilizing the ATmega328 microprocessor, a similar process should be applicable to various Arduino boards. Please note that this guide does not serve as a comprehensive introduction

Stream decks are cool and all, but they are essentially expensive, albeit sorta cool-looking macro pads. So why not try to make your own? You don’t necessarily have to start from scratch. It all started when [dj_doughy] found an extremely clicky num pad in a recycle pile. It was so clicky, in fact, that even though

One of the things missing from the “classic” Arduino experience is debugging. That’s a shame, too, because the chips used have that capability. However, the latest IDE has the ability to work with external debuggers and if you want to get started with a classic ATMega Arduino, [deqing] shows you how to get started with

Description The OPA1662 (dual) and OPA1664 (quad) series of bipolar-input operational amplifiers achieve a low 3.3 nV/√Hz noise density with an ultralow distortion of 0.00006% at 1 kHz. The OPA1662 and OPA1664 series of op amps offer rail-to-rail output swing to within 600 mV with 2-kΩ load, which increases headroom and maximizes dynamic range.

Silicon Labs’ CP2114 device is the industry’s first crystal-less USB-to-I²S audio bridge, designed to support a wide range of codecs and DACs in USB-based audio applications. The CP2114 simplifies the process of transferring audio data from USB to I²S without any code development, speeding time to market for USB audio accessories such as USB speakers,

Mobile PINs are a lot like passwords in that there are a number of very common ones, and [Mobile Hacker] has a clever proof of concept that uses a tiny microcontroller development board to emulate a keyboard to test the 20 most common unlock PINs on an Android device. The project is based on research analyzing the

While building an Arduino Uno based Midi-Controller for Ableton Live, I came across the HIDUINO project ( http://code.google.com/p/hiduino/ ). It allows you to turn your Arduino Uno (or any other device using an AVR-USB chipset like the 8u2) into a driverless HID/Midi device. It’s much more comfortable than using a software based serial to midi

Operating at USB Hi-Speed 480Mbps rate, this fast single channel bridge chip features either a flexible serial interface or parallel FIFO interface, with data transfer speeds up to 40Mbytes/s. Using a serial EEPROM interface, this device can be configured for a wide variety of asynchronous and synchronous serial standards, such as JTAG, SPI, I2C and

The ZIFduino, for all intents and purposes, is an Arduino with a ZIF socket. It’s geared toward those that want to do prototyping on the platform, but then move the ATMega chip to a stand-alone environment. The pin layouts are exactly the same, so it should be compatible with most shields designed for the Arduino.
