How to make an Analog to Digital conversion within the Arduino IDE. If the output voltage is higher than 5V, a method to step it down should be used such as a voltage divider with resistors. When we read an analog pin, the integer that comes back is a discrete level, a number between 0 and 1023. This means that it will map input voltages between 0 and 5 volts into integer values between 0 and 1023. This means that the ADC assumes 5V is 1023 and anything less than 5V will be a ratio between 5V and 1023. The microcontroller monitors the number of clock cycles that pass before the capacitor is discharged. Weird behaviour of timer2 on ATmega328. That is why we used 5.0 and not just 5. Use a trimpot, or light sensor, or simple voltage divider to create a voltage. This yields a resolution between readings of: 5 volts / 1024 units or, .0049 volts (4.9 mV) per unit. If the analog input pin is not connected to anything, the value returned by analogRead() will fluctuate based on a number of factors (e.g. In this tutorial, I will be guiding you through exactly that.
