This project describes how to build an ATSAMD21-based computer on a prototyping board using the minimum number of components, and program it from the Arduino IDE. David Johnson-Davies writes: I give two alternative methods of uploading a bootloader to the bare ATSAMD21 chip using the...

This shield enables you to interface many different devices to Arduino Nano using optically isolated inputs/outputs. The circuit consists of 4 Input channels and 4 Output channels and all 8 I/O lines are optically isolated. This project can help in various industrial applications where...

Arduino has never ceased to impress everyone, and recently have launched the Beta version of their IoT cloud that brings in more awesomeness. The beta version brings autonomy to the Arduino and Makers ecosystem. Now, the connection between an Arduino board and cloud is no more dependent...

A very small narrow-DIP-sized, Arduino Zero compatible USB dev board (OTG enabled), with integrated buck and boost power supplies! The Arduino ecosystem provides an invaluable resource of hardware and software, which allows quick development of a myriad of projects thanks to its...

The Arduino IDE is a great programming tool, it is simple to use and it contains probably all resources one will need to build a project, but evaluating it as a code editor, it is a not the perfect tool. It lacks programming aiding features like IntelliSense, code suggestions,...

ATmega328, FT231X NerO - MCU 8-Bit AVR Embedded Evaluation Board. This is the NERO-SP1, an Arduino compatible module with short shield pin. This Nero module is a reference design for an energy efficient Arduino UNO compatible board based on the ATMEGA328 with the FTDI FT231X USB- UART...

This is an ESP32 Pico D4 project with an accelerometer and 0.69" oled display powered by a rechargeable LIR2450 coin cell. Source files are available on github.com. Mike Rankin writes: I was not made for any specific purpose and was a design challenge to try and made it as small as...

One of the most beautiful things about using the Arduino ecosystem is its stackable ideology, where you can easily add new functionality to almost any Arduino board and make the bare metal Arduino board look so powerful. Hackers can decide to add an IoT add-on, SD storage add-on, or...
