Figure-1 shows the schematic diagram of the device. P1 is used to connect the 220V-AC input and the ON/OFF switch to the circuit. C1 is used to reduce the AC voltage. The value of the C1 also ...
A simple circuit monitors the elapsed time over which a line-connected ac load energizes (Figure 1). You can then access the elapsed-time count over a standard one-wire protocol. When you energize the ...
For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the parts bin and pull out a generic relay of some sort. Relays are ...
