you need to program Arduino to read a sensor and direct the data to the Serial Port. Here, a standard light-dependent resistor (LDR) is used as an analog input sensor and directs its output to the ...

In a nutshell, the Arduino reads the photocell and temperature sensor values and converts them into a data stream, one line of data per program loop that is fed out over the USB port. Again, we don't ...

If you are designing your own intelligent “Graden Computer” with an optional digital plant moisture sensor/water pump controller that lights an LED to alert the user when it is time to water a potted ...

The circuit is extremely simple, comprising the sensor, an Arduino Nano, and an OLED display. This device is handy because its voltage output has a known relationship to the gauss level the sensor ...
