The analog sensor on the Arduino board senses the voltage on the analog pin and converts it into a digital format that can be processed by the microcontroller. Here, we are feeding the input voltage ...

This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture ... This variable resistor is connected in a voltage divider configuration, and Arduino ...

[Paul Stoffregen] proves that it can be pretty easy if you use the CapSense library for Arduino. Here he’s created ... by measuring how long it takes the voltage to change on the input pin.

From the looks of it, his hardware configuration is relatively simple. All it uses is a TSL261 Light-to-Voltage sensor connected to an Arduino with an Ethernet shield attached. The sensor is then ...
