Let’s get practical with some examples of combinations of sensors working at different voltages and references for the A/D converter of Arduino. Third and final part. After getting to know and having studied in details the ADC contained in the ATmega328P microcontroller which is equipped with Arduino Uno board’s and more, and after having…
Let’s go deeper into enhancing techniques for ADC reading and let’s take a look at the first practical examples of analog data reading coming from sensors. Part two. In the first part of this tutorial we have introduced the functioning of Arduino AD converter, which is associated to the input pins A0÷A5 (ANALOG…
Let’s step into the word of analog-digital conversion for Arduino, by discovering how the dedicated pins work and how to use them for acquisitions. Part one. In the ADC of Arduino, an analog signal ranging from 0 to 5 V is translated in 10-bit code, which is 210 = 1024 combinations, with a…
