Observed a 0.4v difference between the actual analog voltage and the voltage read with Internal Analog Reference 1.1v, when an external analog reference voltage is connected to the AREF pin of Arduino ...

Configures the reference voltage used for analog input (i.e. the value used as the top of the input range). The options are: Arduino AVR Boards (Uno, Mega, etc.) DEFAULT: the default analog reference ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal or ...

There was a time when building electronics and building software were two distinct activities. These days, almost any significant electronic project will use a CPU somewhere, or — at least — could.

We all know that the Microcontrollers work only with digital values but in real world we have to deal with analog signals. That’s why ADC (Analog to Digital Converters) is there to convert real world ...

Learning how to do everything on the Arduino can get a little tricky when you're working with a lot of parts. Thankfully, Arduino forum member Romano d'Ezzelino has put together a series of reference ...
