The Vma210 Expansion Board is designed to allow easy access to the interface pins of an Arduino Nano. Each DIO pin or analog pin on the Nano is brought to an appropriate header.

This Module of Switch Reed uses a Small Device called a Leaf Switch. When the Device is Exposed to a Magnetic Field, the Two Ferrous Materials within the Switch are joined together and the Switch closes. When the Magnetic Field is Removed, the Switch Opens.

Control your Arduino projects from anywhere in the world with a free app thanks to the Tuya IoT interface! Connect the Module of Tuya IoT Interface to your Arduino using the 4 included male wires. Then, connect your Arduino to the Cloud IoT Tuya simply by installing the Tuyav library, which is compatible with ATmega Chipsets (or AVR Platform). This will allow you to connect to the Tuya app via WiFi and allow you to control up to 5 outputs.
