What is the main reason beginners are encouraged to use ADC1 pins instead of ADC2 pins on the ESP32?, ADC1 has a higher resolution than ADC2., ADC2 can be unavailable or unreliable when Wi-Fi is in use., ADC1 supports only analog sensors., ADC2 can only measure digital signals., An ESP32 running MicroPython returns an adc.read() value of 4095. What does this indicate?, The ADC detected a hardware fault., The input voltage is approximately at the maximum measurable level., The ADC is operating in 8-bit mode., The input voltage is 5 V., Before converting ADC readings into percentages or using them to control PWM, what is the recommended first step?, Increase the ADC resolution to 16 bits., Enable Wi-Fi to improve ADC accuracy., Verify the raw ADC readings while testing the circuit., Apply attenuation to every analog input.
