The charging principle of wireless chargerWhen current is passed through the coil, a magnetic field is created. When the magnetic flux of the closed-circuit changes, an induced electromotive force is generated.The charging base is responsible for turning the current into a constantly changing magnet Read More »

The qi wireless charger module boards ADC would measure a voltage applied to one of the analog pins, but if you try to measure the voltage you supply, this is "auto-referential." You need to use a function called analogReference() to set the ADC to work with an INTERNAL voltage, regulated and taken Read More »
