Read battery volt by atmega32 microcontroller
WebJul 23, 2016 · It really depends on how much work your 328 has to do. At 20MHz/5V, an active 328 draws about 20mA = 100mW, but at low clock speed and voltage, 1mW is very doable. Big difference. When operating at low voltages, close to the tolerance of the 328, you might also want to consider how to deal with battery voltage drop. WebJul 3, 2015 · In ATMEGA32A, the ADC is of 10 bit resolution, so the controller can detect and sense a minimum change of Vref/2^10, so if the reference voltage is 5V, we get a digital …
