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 ...

The AD4116 is a low power, low noise, 24-bit, Σ-Δ analog-to-digital converter (ADC) that integrates an analog front end (AFE) for six fully differential or eleven single-ended, high impedance (≥10 MΩ) ...

Here is a useful circuit for Arduino lovers and experimenters. It is a simple digital voltmeter, which can safely measure input dc voltages in 0 to 30V range. The Arduino board can be powered from a ...
