In this experiment we are going to use a element called photoresistor. This sensor allows us to interact with the external environment, through intensity of light. The photoresistor is based on light ...

I connected one soil probe to power, and the other to ground through a 10kΩ resistor and to Arduino's analog pin A0. I did the same with the thermistor and photoresistor, but connected those to ...

In this particular project, I contemplated a shield for Arduino Nano, which can gather weather-related information by a built-in BMP280 Temperature and Pressure Sensor, a photoresistor, and a ...
