The WiFi Relay Shield is an Arduino compatible module that provides an easy way to control high voltage loads thanks to 4 independent channels equipped with photo-coupled mechanical relays ...

Currently the arduino sketch broadcasts its IP address every 10s on UDP port 8981. Eventually it will use SSDP (which is supported by the Hubitat driver framework). The default MAC address should give ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

The Arduino GIGA Display Shield is a 3.97-inch RGB touchscreen display designed for the Arduino GIGA R1 WiFi board introduced a few months ago with an STM32H7 dual-core Cortex-M7/M4 microcontroller ...

When developing electronic projects, the power supply is one of the most important part of whole project and there is always need of multiple output voltage power supply. This is because different ...

Aspinity AB2 AML100 is an Arduino Shield based on the company’s AML100 analog machine learning processor that reduces power consumption by 95 percent compared to equivalent digital ML processors, and ...

So, what do you do when your Arduino project needs to operate in a remote area or as a portable device? There are LiPo battery shields available, and although they may work well, recharging requires ...
