Has anyone used a 16 Channel 12V Relay Module Interface Board For but I have no idea how to do so, I’m looking for a schematic and a code example.
garden bot and thought this would be the best way also how to wire on the arduino. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits.
This 8 channel 5V relay has both . Instructions, schematics and tutorial for the popular 4 channel relay module used with arduinos. Fundamentally this is four separate circuits on one board.

SainSmart is an open hardware manufacturer specializing in maker products ranging from 3D Printer and 3D Filament, CNC Router, Robot Arm, Arduino, Raspberry Pi etc.
Since , SainSmart has supplied a variety of open hardware supplies to help turn daydreams and . In a little documented stroke of luck the relay module has a separate loop to power the relay coils, that is the electromechanical part that makes the relay switch, and the Pi has a +5V pin to supply power directly from the USB power source. The 2 standalone pins on the relay module marked VCC and ground should go to the Pi’s +5V and Ground pins.
There is a schematic available as one of the product photos on the page you linked: This shows that of the three contacts associated with each relay, the center one is the common connection, one of the others is a normally-open contact, and the third is normally-closed. The simplest solution for on/off Home Automation is to use pfodDesignerV2 to design your control for upto 4 switches and then use a Arduino Uno + Bluetooth module + 4 channel relay board powered by a USB power supply and controlled by pfodApp and, if switching mains power, have an electrician wire it in.How to wire a Raspberry Pi to a Sainsmart 5v Relay Board – Raspberry Pi ForumsHome Automation How to Add Relays to Arduino
