Measuring 20V alerts on an Arduino Uno with a quantizer – Open Electronics
Residence Information Measuring 20V alerts on an Arduino Uno with a quantizerBy Marco Ventimiglia on July 26, 2022As we all know, Arduino Uno features a 10-bit ADC (analog-to-digital converter) inside its ATmega328p, which takes a sign between 0 and 5V and produces a digital worth that varies from 0 to 1023. Nevertheless, attempting to measure any voltage above 5V will trigger some lower than fascinating outcomes, comparable to creating magic smoke and destroying the microcontroller. To get round this, some makers add a voltage divider that divides the enter voltage by a predetermined issue. This answer reduces the…
