This is a simple arduino project for a soil moisture sensor that will light up a LED at a certain moisture level. It uses Arduino Duemilanove microcontroller board. Two wires placed in the soil pot ...

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 ... here is an Arduino Primer ...

What happens when an engineer builds a smart garden? This Arduino-powered system automates watering while collecting ...

Arduino soil moisture sensors are easy to use ... Arduino pulse sensors have a small infrared LED that is placed on a finger to reliably read the pulse of a human, providing an analog output ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy ...

As the soil dries out, the sensor value rises; when it reaches 900, the LED will light and the buzzer will sound. The sketch first defines Arduino pin A0 so that it reads the moisture sensor value. It ...

As you get more comfortable, you can add moisture sensors and assign ... and an LED display. Assembly is straightforward: Connect the components to the Arduino controller, and then dive into ...

[electron_plumber] made an LED that can be blown out like a candle, and amazingly it requires no added sensors. The project uses an Arduino to demonstrate turning a tiny LED on and off in ...
