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 ...

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 ...

This is an accurate LM35 analog temperature sensor library for Arduino with noise cancellation. This library changes analog pins to ADC 1.1V internal reference voltage which affects all analog pins.

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 ...

Engineers always want to get all they can from their circuits; this holds for analog-to-digital converters (ADCs). To maximize performance from an ADC, resolution is perhaps the primary spec to focus ...
