Circuit Connection

Hardware

At first, I mount all the components in the zero pcb.  then I soldered all the components into the zero pcb using my schematic. you can download the schematic.

And I connect all the wires between the relay and the appliance(bulb). The connection between the relay and the bulb is -

          Input red wire to relay common point

          Bulb's red wire to relay NO point

          Input black wire to bulb's black wire

After soldering all the components into the zero PCB, I attached my circuit to the enclosure.
