The author noticed that the AC line frequency changes in spans of 0.4 Hz and periods of several minutes, so I wanted to examine long-term changes in AC line frequency and voltage. This is a project to build a line voltage frequency monitor. It is not a complete instrument but a simple measurement adapter designed to be embedded in some measurement system with a PC or microcontroller.
