# Sampling rate analog to digital converter

I am a novice in microcontroller subject and have just learned that ADC converts analogue voltage on a pin of, for example, an Arduino, to a binary number. Since the ADC on the Arduino is a 10 bit ADC, we will have 210 discrete analogue levels. Does it mean that the number of samples during the acquisition time is 210 and the intervals between these samples gives the sampling time?

Edit:So here in the picture with two bits we have 4 levels. When I look at this graph I see the signal has been sampled 4 times equal to 22.

• No, it means that each sample is converted to an integer value between 0 and 1023 $(0\rightarrow 2^{10}-1)$

• Well wouldn't that make the number of samples 1024?

• No, it means that each voltage sample is converted to a binary number between 00 0000 0000 and 11 1111 1111

• One ADC reading is one sample, as far as the user is concerned. Sep 16, 2015 at 16:36
• Could you please take a look at the edit I made to my question.
