The shield uses HV5812 drivers to handle the high-voltage side of things, a part more typically used to drive vacuum fluorescent displays. There’s also a DHT22 for temperature and humidity ...

The ‘under’ in Undershield comes from this shield being mounted underneath the Arduino, unlike every other shield on the planet.

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 ...

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.

OMC has launched a fibre optic transceiver shield for Arduino Uno, designed to work with PMMA (polymer) optical cables up to 25m long, plus demonstration software.

Arduino have taken the tiny wraps off of the official ethernet shield for their open-source prototyping platform, which adds network connectivity to the device. Based… ...

Mayhew Labs have unveiled a new DAC add-on board they have created for the Arduino platform in the form of the Extended DAC Shield that takes the form of a high-speed, precision, eight channel ...

To interface with the Arduino Uno, you’ll need a custom shield that houses essential components such as relays, transistors, power supplies, and an operational amplifier.
