Using an NPK Sensor with Arduino

arduino NPK sensor wiring diagram

We’ve featured in a previous project how we can make a “plant” send messages when it needs more water. Of course, healthy plants don’t only need water; the soil in which they are planted must also be abundant in a number of chemicals. Is there a sensor that does this?

Arduino Programming: Ternary Operator


If your Arduino code involves decision-making, then it's very likely you're using conditional statements. Using if ... else... is common;  switch statements as well. But there is a third way, using ternary operator, that will really make your code shorter.   Example Scenario Say we are reading the state of …
