Hope someone can help me. I need a sketch for detecting AC current and then activating a 30a relay.
This system will detect use of power tools and then activate additional equipment. the tools that will be used are all 220v and vary between 300w and 1500w. a 2sec start and 10sec stop time will also be required.
I will use a 30a acs712, Arduino UNO or Micro and 30a relay and of course a apropriate power supply.
Any help or nuge to the correct forum will be apreciated as i am very new to coding,
