Arduino Addons: Battery Level Indicator - Hacksterio
/7/2016I have an mcp73833 board which i connected to the battery(3. 7v 2200mah) forever, and it is running the arduino mega. Is there any indication of discharging to send to arduino so that arduino can open relay to the charging connection to charge the battery withaout actual power off the arduino?

ARDUINO based SWR and RF POWER Meter. How to calibrate the power indication ? Using a directional coupler which is not frequency compensated, the forward voltage (indicating the power) will be frequency dependant. For a 'monimatch' type, the voltage will increase with frequency - or - otherwise said, the meter will become more sensitive at
