There are many applications when a remote switch’s on/off status needs to be monitored. Reed relay sensors, toggle control switches and security alarms contacts are just a few examples. Routing a switch directly to a computer system hundreds ...
I have modified several commercial solar garden lights over the years. I switch out the LED, solar panel, battery pack and control circuit. The result is a much better overall light. One of my disappointments in using store-bought garden light ...
Simple linear and switching voltage regulators with feedback networks of the type shown in Figure 1 are legion. Their output voltages are the reference voltage at the feedback (FB) pin multiplied by 1 + R F /R G . Recommended values of C F from 100 ...
It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated circuit, and switching can be relatively slow and ...
