Programming for Soil Monitoring using IoT. There are two parts of programming in this Smart Water Monitoring System using IoT. In the first part, Arduino is programmed and in the second part, NodeMCU ...

The Arduino Monitoring and Control System is a simple Arduino-based program designed to read analog sensor values, control digital outputs, and display information on an I2C LCD display. The system ...

The water pump and servo motor are controlled by Arduino connected to digital pins 3 and 9, respectively. That is, the servo motor signal control pin is connected to pin 9 of the Arduino board. Fig. 2 ...

Water Tank Filling System Code. Arduino Uno IDE is used here. In the Arduino code, the behaviour of the hardware components is defined based on the methodology mentioned earlier. Fig. 3: Arduino code ...

With that out of the way, your Arduino’s built-in LED should start blinking once every second. If you really want to see it work on an external LED, then you should try putting an LED and a 250 Ω ...

However, to transmit serial data (such as debugging information) wirelessly, we need another solution. IoT devices operating remotely ‘in the field’ benefit from the ability to perform software ...
