WiFi Energy Monitor
My new project consists of HW with cost under 20€. It is able to accurately measure electric power consumption and sends data via WiFi. Great source of knowledge is openenergymonitor.org which includes also Arduino library.
Program ATtiny13A via Arduino board
Programming ATtiny micro-controller is quite easy if you have all the needed information in one place. That is the reason to put all needed files, hints in one post so next time I will need it,[…]
Simple Low Voltage Disconnect Circuit for Arduino
I have read several forums regarding the disconnecting the Arduino power from the Lithium Ion battery by itself (measuring the battery voltage and when the low limit is reached the Arduino signal turns off itself).
