Arduino Wattmeter: Measure Voltage, Current and Power Consumption

Metering – Instrument Projects / By

As electronics engineers, we always depend upon meters/instruments to measure and analyse the working of a circuit. Starting with a simple multimeter to a complex power quality analysers or DSOs everything has their own unique applications. Most of these meters are readily available and can be purchased based on the parameters to be measured and […]

Disconnect circuit for 12 volt lead acid and lithium batteries

Electronics News Updates / By

There are two things that you don’t want to do with any rechargeable battery on a routine basis: Overcharge it. Overdischarge it. While the above are true for lead-acid batteries, they are particularly true of Lithium-Ion chemistries, but for different reasons. With Lead-acid batteries: Lead-acid batteries – particularly the “flooded cell” types (e.g. those to
