analogRead()DescriptionReads the value from the specified analog pin. The Arduino board contains a 6 channel (8 channels on the Mini and Nano, 16 on the Mega), 10-bit analog to digital converter.
25 Dec 2019 So I am doing a dual-axis solar tracker using LDR sensors and I hooked up my RPi 4B to my Arduino Uno so the Arduino can do analogRead()
2021-04-15 · Arduino boards contain a multichannel, 10-bit analog to digital converter. This means that it will map input voltages between 0 and the operating voltage(5V or 3.3V) into integer values between 0 and 1023. On an Arduino UNO, for example, this yields a resolution between readings of: 5 volts / 1024 units or, 0.0049 volts (4.9 mV) per unit. analogRead() function. In Arduino programming, we will use an AnalogRead function that is used to measure the voltage between 0 to 5 volts and convert this voltage into integer values between 0 and 1023.

AnalogRead() Function Arduino Arduino AnalogRead function is used to measure the voltage between 0 to 5 volts and converts it into a digital value between 0 to 1023. The reason for value 1023 is because the analog to digital converters is 10-bit long. Arduino IDE has a built-in analogRead function to facilitate the conversion of analog values to digital.
