Description:
This project is to drive the automation board remotely. Arduino Nano will be configured as a WebServer providing a html page for viewing and triggering the IOs of the card.
Hardware:
1 – Arduino NANO V3.0
1 – Nano Automation Shield Board, on sale in our online store.
1 – 12V power supply
1 – Shield W5100 – MiniShield or Ethernet Shield
3 – Power switches
3 – 10K resistors
16 – Wires with MODU connectors for project connection Project connections with mini shield
Connection with Ethernet Shield:
