The board consists of 8 x RGB LEDs 1W, BJT transistors on each LED, series resistor across the LED for current limiting, a hole to mount 18mm optical sensor which may be a defuse sensor for object detection with Arduino nano.  The board can be programed to create multiple RGB LED...

The kit is available for ESP32 modules to offer developers cost-effective data transmission via sound waves. Chirp, the pioneers in data-over-sound technology today announced the launch of its new SDK for Arduino, providing developers with audio-based data transmission capabilities to...

Miniduino is a small (19x40x3,5 mm, pin-strip and USB connector excluded) Arduino board with minimal hardware, but with access to all I/O like the Nano board and equipped with a USB connector with direct insertion integrated into the PCB: practically an Arduino Pen Drive. The board is...

Home automation refers to the ability of your home to make its own decisions depending on environment conditions and give you the option to control it from a remote location. In one of our previous tutorial on the ESP8266 WiFi Module, we examined how NodeMCU or any of the other ESP8266...

Weather stations are interesting projects for beginners and very useful for expert makers. They are usually quite simple to build but also provide fairly accurate and useful weather data. We have built a couple of them in different tutorials on this website, with the difference usually...

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...
