Webvalue ¶ The value on the analog pin between 0 and 65535 inclusive (16-bit). (read-only) Even if the underlying analog to digital converter (ADC) is lower resolution, the value is 16-bit. reference_voltage ¶ The maximum voltage measurable (also known as the reference voltage) as a float in Volts. WebNov 25, 2024 · Digital signals only can ever have two states, they are either are on(high logic level voltage like 3.3V) or off(low logic level voltage like 0V / ground). By contrast, analog signals can be any voltage in-between on and off, such as 1.8V or …
WebJun 8, 2016 · battery_percentage = (bus_voltage - 3.0) / 1.2 Because the battery cuts out at 3.0volts, and has a 'Charge Cut-Off Voltage' at 4.2. I realize this makes the voltage linear, and really its a curve...but i figured it'd give me an approximation at least.

WebJul 11, 2024 · You can connect with a USB cable (just plug into the jack) and the Feather will regulate the 5V USB down to 3.3V. You can also connect a 4.2/3.7V Lithium Polymer (LiPo/LiPoly) or Lithium Ion (LiIon) battery to the JST jack. This will let the Feather run on a rechargeable battery. WebNov 21, 2024 · The basic operating idea is: The battery voltage was divided by 1/2 with 200k and connected to the A0 port so that the voltage could be monitored. The datasheet says nominally 2500mV full scale AD conversion, but there is a large variation from chip to chip, actually ±10%. My chip was 2700mV full scale.
