Step 1: Safety First!
This instructable is intended only for someone experienced and confident in wiring high voltages. Do not attempt to do this if you are not. Household current can kill or badly injure you if you who do not understand the danger.
Only the U451 relay contacts should be used for control/connection to 110V AC. The relay screw terminals are isolated from the other circuit connections. DO NOT touch the U451 when there is 110V AC present.
Step 2: Major parts
- USB relay interface USBmicro U451
- two light bulbs
- lamp sockets
- 110V AC cord
Step 3: Project mounting board
Step 4: Board parts
The lamp sockets in this example setup will rest on some washers to provide some space for the wires that lead out from the under side of the socket and to the U451.
